摘要：

Multinuclear, variable temperature NMR spectroscopic experiments show that: (i) treatment of [{Pt(LL)}(2)(mu-LL)], 1, with an 2 excess of (CH2=CHSiMe(2))(2)O (=LL) yields [Pt(LL)(LL)], 2; (ii) treatment of 1 with PhCH=CH2 gives [Pt(LL)(eta(2)-CH2=CHPh)] 3; and (iii) reaction of cis-[Pt(eta(2)-CH2=CHPh)Cl-2] with LL yields successively 1, 2, and 3. The pathway in the case of (iii) involves initial chloride-vinyl exchange, followed by reductive elimination in which vinyl radicals and vinyl chloride may be involved.
