Synthesis, molecular structure, substitution and C–C coupling reactions of ruthenium complexes containing (η5-C9H7)Ru(PPh3) as a molecular unit

Indenyl complexes of ruthenium containing thiolate ligands. Structure of IndRu(dppe)SPh

“…spectra of these complexes show, as expected, a doublet in the 3.97-3.99 ppm range and a triplet in the 4.66-4.67 ppm range, for the C 5 -ring protons of the indenyl group. These values are lower than those for [(g 5 -C 9 H 7 )Ru(PPh 3 ) 2 Z]PF 6 {Z=C 2 H 4 ,O=C(CH 3 ) 2 doublet: 5.70-5.73 ppm, triplet: 4.73-5.04 ppm [5], and also lower than those for the starting complexes (g 5 ) C 9 H 7 )Ru(PPh 3 ) 2 R, (1) . The 31 P-n.m.r.…”

“…They are soluble in THF, acetone, benzene and ethanol and insoluble in hexane. The compounds have been characterized by 31 [30], and they fall in the range reported for IndRu(PPh 3 ) 2 X complexes (X = H, CH 3 ) [5]. The 31 P-n.m.r.…”

“…Selected bond lengths and bond angles for (2b) are shown in Figure 1 caption. The Ru-C bonds of this ligand ranging from 2.1987 (17) [5] and to the analogous Cp-complexes, (e.g. CpRu(dppe)SCO 2 Bu n : 2.200(2)-2.240(2) Å , CpRu(PPh 3 ) 2 SCO 2 Bu n : 2.202(2)-2.230(2) Å ) [28].…”

“…The chemistry of ruthenium complexes with indenyl and phosphine ligands has developed rapidly within the last decade and is still of great interest [1][2][3][4][5][6][7][8]. These complexes have been known as catalysts in many useful organic reactions [9][10][11][12][13][14][15][16][17][18].…”

Heterobimetallic Pd–Sn Catalysis: A Suzuki, Tandem Ring-Closing Sequence toward Indeno[2,1-b]thiophenes and Indeno[2,1-b]indoles

“…Using PdCl(COD)SnCl 3 C1 alone, we observed negligible formation of 4a (entry 1, Table ). Gratifingly, the reactivity of C1 was dramatically enhanced in the presence of AgPF 6 (entry 3) . Individually AgPF 6 as well as PdCl 2 (COD)/AgPF 6 , SnCl 2 /AgPF 6 , PdCl 2 /AgPF 6 , and [PdCl(PPh 3 ) 2 SnCl 3 ]/AgPF 6 were ineffective toward the cyclization of 3a .…”
