Synthesis and Characterization of the First Transition-Metal eta(2)-Disilene Complexes. (Reannouncement with New Availability Information).

摘要

The preparation of the first N2-transition metal-disilene complexes, (R2PCH2CH2Pr2)-Pt(R2'SiSiR2'), 3 (a: R = Ph, R' = i-Pr, b: R = cyclohexyl, R' = Ph) is reported. These novel platinum complexes are characterized by 1H, 31p, 29Si NMR, MS and elemental analyses. An oxidative addition-reductive elimination mechanism is proposed for the formation of 3.
