在寻找基于钼的腈-炔交叉复分解(NACM)催化剂时,已经合成了N≡Mo(OR)3类型的配合物(R =叔烷基,叔甲硅烷基,大体积的芳基)。已知N≡Mo(NMe 2)3的质子分解导致形成N≡Mo(O-2,6- i Pr 2 C 6 H 3)3(NHMe 2)(12),N≡Mo(OSiPh 3)3(NHMe 2)(5 -NHMe 2)和N≡Mo(OCPh 2 Me)3(NHMe 2)(17 -NHMe2)。的X射线结构12显示了一个NHMe 2配体结合的顺向氮基配体,而5 -NHMe 2所具有的NHMe 2结合反式的氮化物配体。因此,17 -NHMe 2容易失去其胺配体而形成N≡Mo(OCPh 2 Me)3(17),而12和5 -NHMe 2将其胺配体保留在溶液中。从体积较大的三苯胺配合物开始,N≡Mo(N [R] Ar)3(R =异丙基,叔丁基 Ar = 3,5-二甲基苯基)允许形成无碱的配合物N≡Mo(OSiPh

Terminal Phosphide and Dinitrogen Molybdenum Compounds Obtained from Pnictide-Bridged Precursors
摘要:
The syntheses of molybdenum terminal phosphide and dinitrogen complexes supported by N-isopropylanilide ligands are not as straightforward as those previously reported for the analogous N-tert-butylanilide complexes, To arrive at these synthetic targets, facile, high-yielding syntheses of bridging pnictide precursors have been developed, and their reduction chemistry has been explored. Cleavage of the reduced mu -E-1 compounds was undertaken using CO and N-2, providing access to the target compounds.
