The reactivity of a series of organometallic rare earth and actinide complexes with hemilabile NHC-ligands towards substrates with acidic C-H and N-H bonds is described. The synthesis, characterisation and X-ray structures of the new heteroleptic mono- and bis(NHC) cyclopentadienyl complexes LnCp2(L) 1 (Ln = Sc, Y, Ce; L = alkoxy-tethered carbene [OCMe2CH2(1-C{NCHCHN(i)Pr})]), LnCp(L)2 (Ln = Y) , and the homoleptic tetrakis(NHC) complex Th(L)4 4 are described. The reactivity of these complexes, and of the homoleptic complexes Ln(L)3 (Ln = Sc 3, Ce), with E-H substrates is described, where EH = pyrrole C4H4NH, indole C8H6NH, diphenylacetone Ph2CC(O)Me, terminal alkynes RC≡CH (R = Me3Si, Ph), and cyclopentadiene C5H6. Complex 1-Y heterolytically cleaves and adds pyrrole and indole N-H across the metal carbene bond, whereas 1-Ce does not, although 3 and 4 form H-bonded adducts. Complexes 1-Y and 1-Sc form adducts with CpH without cleaving the acidic C-H bond, 1-Ce cleaves the Cp-H bond, but 2 reacts to form the very rare H(+)-[C5H5](-)-H(+) motif. Complex 1-Ce cleaves alkyne C-H bonds but the products rearrange upon formation, while complex 1-Y cleaves the C-H bond in diphenylacetone forming a product which rearranges to the Y-O bonded enolate product.

The emergence of “big research” has given rise to a variety of organizational environments (e.g. powerful research labs, projects and centres) that complement and transcend the traditional departmental structures of universities. Success in building and sustaining these “organized research units” and in reconciling their competing interests is central to the mission of a research university. In this preliminary study, we focus on individual experiences of working in cross-disciplinary research projects and centres within a large research university. Through interviewing key individuals (project leaders, academic and non-academic staff) engaged in running large research projects and/or centres, we aim to unpack the diversity and dynamics of different institutional logics at work at different stages of the organized research unit (ORU) life cycle. We seek to draw general conclusions in terms of managing and reconciling the research missions of ORUs, the university, and its external stakeholders (government, industry and society in general). This paper was submitted to the 35th European Group for Organizational Studies colloquium (EGOS2019). A longer version of this paper, which interprets our results from the perspective of Mode 2 knowledge production, is available at SocArXiv ("Nurturing Project Organizations: A Mode 2 Mission for the University?").

A set of β-ketoimidazolium and β-ketoimidazolinium salts of the general formula [R(1)C(O)CH2{CH[NCR(3)CR(3)N(R(2))]}]X (R(1) = (t)Bu, naphth; R(2) = (i)Pr, Mes, (t)Bu; R(3) = H, Me, (H)2; X = Cl, Br) show contrasting reactivity with superhydride bases MHBEt3; two are reduced to chiral β-alcohol carbene-boranes R(1)CH(OH)CH2{C(BEt3)[NCR(3)CR(3)N(R(2))]} 2 (R(1) = (t)Bu; R(2) = (i)Pr, Mes; R(3) = H), two with bulky R(2) substituents are reduced to chiral β-borate imidazolium salts [R(1)CH(OBEt3)CH2{CH[NCR(3)CR(3)N(R(2))]}]X 3 (R(1) = (t)Bu, naphth; R(2) = Mes, (t)Bu; R(3) = H, Me; X = Cl, Br), and the two saturated heterocycle derivatives remain unreduced but form carbene-borane adducts R(1)C(O)CH2{C(BEt3)[NCR(3)CR(3)N(R(2))]} 4 (R(1) = (t)Bu, naphth; R(2) = Mes; R(3) = (H)2). Heating solutions of the imidazolium borates 3 results in the elimination of ethane, in the first example of organic borates functioning as Brønsted bases and forming carbene boranes R(1)CH(OBEt2)CH2{C[NCR(3)CR(3)N(R(2))]} 5 (R(1) = naphth; R(2) = Mes; R(3) = Me). The 'abnormal' carbene borane of the form 2 R(1)CH(OH)CH2{CH[NC(BEt3)CR(3)N(R(2))]} (R(1) = (t)Bu; R(2) = (t)Bu; R(3) = H), is also accessible by thermolysis of 3, suggesting that the carbene-borane alcohol is a more thermodynamically stable combination than the zwitterionic imidazolium borate. High-temperature thermolysis also can result in complete cleavage of the alcohol arm, eliminating tert-butyloxirane and forming the B-N bound imidazolium borate 7. The strong dependence of reaction products on the steric and electronic properties of each imidazole precursor molecule is discussed.

Recent changes in UK research funding priorities have led to the emergence of large challenge-led, societally embedded research opportunities. We used semi-structured interviews with 27 academic, management and professional staff at the University of Edinburgh to explore the life cycles of selected projects and centres from planning and preparation through to decommissioning. We observed the degree to which pursuit of challenge-led opportunities induced the emergence of new project-level organizational forms or changed academics’ modus operandi from “Mode 1” research to “Mode2” knowledge production. We further explored the levels of management input and administrative support expected and received by the project organization from its host academic schools, colleges the university. We found that the size, complexity and disciplinary, interdisciplinary or transdisciplinary scope of the initiatives influenced their emergence as autonomous project organisations. “Role strain” affected many respondents as they sought to balance Mode 1 academic and Mode 2 leadership and management roles in their project organizations. Further exploration of the distribution of leadership management and professional support functions among project organizations and the support structures of academic schools, colleges and the university is warranted. We suggest that the university might usefully act as a boundary organization and adopt a Mode 2 knowledge exchange mission in support of multi-stakeholder projects. This paper was submitted to the 35th European Group for Organizational Studies colloquium (EGOS2019). A shorter version of this paper, which focuses on the institutional logics observed among the university staff, is also available at SocArXiv ("Nurturing cross-disciplinary research: Institutional logics, hybrid Spaces and meta-organization at a research university").
