Synthesis of nido- and closo-diplatinacarborane Complexes by Direct Insertion; Crystal and Molecular Structures of closo-2-3-((Et3P)2)2-1-2-3-6-CPt2CB5H7-nido-4-8-((Me3P)2Pt)-8- 8((Me3P)2)-7-8-10-CPtCB8H10 and nido-8-8-((Me3P)2)-7-8-10-CPtCB8H10.

摘要

Reaction of closo-2,4-C2B5H7 with (Pt(styrene)(PEt3)2) affords closo-2,3-((Et3P)2)2-1,2,3,6-CPt2CB5H7 whereas (Pt(1,5-C8H12)(PMe3)2) and 1,6-C2B8H10 gives nido-micrometer(4,8)-((Me3P)2Pt)-8,8-((Me3P)2)-7,8,10-CPtCB8H10 which on treatment with activated charcoal affords nido-8,8-((Me3P)2)-7,8,10-CPtCB8H10; the structural identity of the complexes was established by X-ray crystallography.
