proposed for the formation of the unsymmetrical dinuclear complexes (8 and 15) that involves a bimolecular reaction between two mononuclear species, (Ph3P)2Pt(H)(SiAr2H) and (Ph3P)Pt(H)(SiAr2H). VT-NMR studies of complexes 8 and 15 illustrate that a fluxional process occurs which can be explained by elimination and recoordination of a PPh3 ligand. Complex 15 reacted with added P(p-Tol)3 to produce a mixture
通式(Ph 3 P)2 Pt(H)(SiAr 2 H)和(Ph 3 P)2 Pt(SiAr 2 H)2的单核含Pt-Si配合物是在低温下从次级arylhydrosilanes博士2的SiH 2,C 12 H ^ 8的SiH 2(silafluorene),和C 20 ħ 24的SiH 2(3,7-二-叔-butylsilafluorene)与(PH 3 P)2
铂(η 2 -C 2 ħ 4)。当单核配合物的溶液在低温下运行,然后升温至室温时,或者当反应在室温或更高温度下运行时,会生成含双核Pt-Si的配合物,[(Ph 3 P)Pt(μ- η 2 -HSiAr 2)] 2(AR =苯基(4))和[(PH 3 P)2
铂(H)(μ-SIAR 2)(μ-η 2 -HSiAr 2)的Pt(PPH 3)]( Ar 2 = C 12 H 8(8),C 20 H 24(15); 两者都是通量的)。提出了形成
