Template‐Controlled Assembly of Ditopic Catechol Phosphines: A Strategy for the Generation of Complexes of Bidentate Phosphines with Different Bite Angles

“…The template sources used included various chlo-A C H T U N G T R E N N U N G rides of tri-and tetravalent main group elements (AlCl 3 , GaCl 3 , SiCl 4 , SnCl 4 , BiCl 3 ), as well as ZrCl 4 , chosen because of their known ability to form stable catecholate complexes. [13][14][15] Furthermore, aluminium and gallium are larger congeners of boron, whereas Ga III , thanks to its similar ion radius, is a mimic of Fe III , an important component in biological [16] and redox processes. [17] Last, but not least, zirconium oxide materials are receiving increasing interest as supports for palladium-based cross-coupling catalysts [18] and with regard to the application of tin compounds as cocatalysts during palladium-catalyzed carbonylation, [19] Pd/Sn bimetallic complexes might have interesting potential in catalysis.…”

Template controlled self-assembly of bidentate phosphine complexes with hemilabile coordination behaviour

“…In view of the existence of stable spirocyclic catecholate complexes of tin 9 we began to study reactions of two molar equivalents of the phosphine L 1 with [PdCl 2 (COD)] (1) and SnCl 4 or Me 2 SnCl 2 , respectively. The reaction proceeded readily in DMF-NEt 3 via self-assembly to afford the complexes 2a,b (Scheme 2) which were isolated in moderate to good yield.…”

Second-order nonlinear optics in coordination chemistry: An open door towards multi-functional materials and molecular switches

“…4), and (ii) targeted experimentally within the conditions of the EFISH experiment, in which the chromophores are submitted to pulses of intense electric fields. [39]), tris-catecholato stanate(IV) (center -see ref [41], and tetrahedral organotin (bottom-see ref [42]) chromophores.…”
