  Sterically hindered diphosphines (Ph₂P)₂CCHR (R = Me or Ph) and their derivatives

  摘要：

  Reactions of (Ph2P)2C=CHR (R = Me or Ph) with E (E = S or Se) yielded the corresponding mono- and di-chalcogenides and the mixed S/Se derivatives, H-1, C-13 and P-31 NMR parameters for which are reported. These are rationalized in terms of conformational preferences associated with the relative P-E and phosphorus-lone pair orientations. The complexes [M(CO)4{(PhP)2C=CHR}] (M = Mo or W, R = Me or Ph) have also been prepared and have NMR parameters which can be accounted for similarly. The crystal structure of (Ph2P)2C=CHMe has been determined by single-crystal X-ray diffraction and shows that the solid-state conformation is similar to that deduced in solution on the foregoing basis.

  The synthesis of two novel titanium carbene complexes from the bis(thiophosphinoyl)methanediide geminal dianion 1 (SCS2−) is described. Dianion 1 reacts cleanly with 0.5 equivalents of [TiCl4(thf)2] to afford the bis‐carbene complex [(SCS)2Ti] (2) in 86 % yield. The mono‐carbene complex [(SCS)TiCl2(thf)] (3) can also be obtained by using an excess of [TiCl4(thf)2]. The structures of 2 and 3 are confirmed

  The stabilized anion [Ph2P(S)]2CH}− with lithium as counter cation 1a reacts with formaldehyde or benzaldehyde to give vinylidene phosphine sulfides [Ph2P(S)]2CCHR, where R is H or Ph, respectively (3, 4). The same anion with potassium as counter cation 1b gives vinyl phosphine sulfides (9−11). The formation of these two different classes of compounds is dependent on the the cation and the solvent
