摘要

The trichlorostannyl complexes M(SnCl3)(CO)(n)P5-n (1-3: M = Mn, Re; P = PPh(OEt)(2) (a), P(OEt)(3) (b); n = 2, 3) were prepared by allowing chloro MCl(CO)(n)P5-n compounds to react with an excess of SnCl2 center dot 2H(2)O. Treatment of compounds 1-3 with NaBH4 in ethanol yielded the tin polyhydride derivatives M(SnH3)(CO)(n)P5-n (4-6). Treatment of 1-3 with MgBrMe gave the trimethylstannyl complexes M(SnMe3)(CO)(n)P5-n (7-9), and the reaction of 1-3 with MgBr(CCH) yielded the trialkynylstannyl derivatives M[Sn(CCH)(3)](CO)(n)P5-n (10, 11). The alkynylstannyl complexes M[Sn(CCR)(3)](CO)(n)P5-n (12-14: R = p-tolyl) were also prepared by allowing M(SnCl3)(CO)(n)P5-n compounds to react with Li+[CCR](-) in thf. The complexes were characterized by spectroscopy and by X-ray crystal structure determinations of 4a, 6b, and 9b. Reaction of the tin trihydride complexes Re(SnH3)(CO)(2)P-3 (6) with CO2 (1 atm) led to the binuclear OH-bridging bis(formate) derivatives [Re{Sn[OC(H)O](2)(mu-OH)}(CO)(2)P-3](2) (15). A reaction path for the formation of 15, involving the tin hydride bis(formate) intermediate Re[SnH{OC(H)O}(2)](CO)(2)P-3, is discussed. The X-ray crystal structure of 15b is reported.
