Reduction of α,β-unsaturated ketones and esters with triphenyltin hydride or tributyltin hydride in the presence of triethylborane has been studied. Whereas the reaction of α,β-unsaturated ketones (R1CH=CHCOR2) with triphenyltin hydride provided the corresponding saturated ketones (R1CH2CH2COR2), treatment of α,β-unsaturated ester (PhCH=CHCOOMe or CH3CH=CHCOO–n-C6H13) afforded an adduct (PhCH2CH(SnPh3)COOMe
已经研究了在三乙基硼烷存在下用氢化三苯基锡或氢化三丁基锡还原 α,β-不饱和酮和酯。α,β-不饱和酮(R1CH=CHCOR2)与氢化三苯锡反应生成相应的饱和酮(R1CH2CH2COR2),而α,β-不饱和酯(PhCH=CHCOOMe 或 CH3CH=CHCOO-n-C6H13)的处理得到加合物 (PhCH2CH(SnPh3)COOMe 或 CH3CH(SnPh3)CH2COO–n-C6H13)。
