Chiral tin(IV) derivatives with two or three chiral centers adjacent to the metal (−)-Ment2SnMe2, (−)-Ment2SnPh2, (−)-Ment3 SnCl, (−)-Ment3SnH; (−)-Ment (1R, 2S, 5R)-1-chloro-5-methyl-2-isopropylcyclohexane, R2Sn[CH(Me)(n-Hex)]2 (R Bu or Ph) have been prepared either by the coupling of methylmagnesium chloride with tin halides or by the reaction of lithium stannates with optically active (2-octyl)tosylate
具有与金属(-)-Ment 2 SnMe 2,(-)-Ment 2 SnPh 2,(-)-Ment 3 SnCl,(-)-Ment 3 SnH ,金属相邻的两个或三个手性中心的手性锡(IV)衍生物;(-)-(1R,2S,5R)-1-氯-5-甲基-2-异丙基环己烷,R 2 Sn [CH(Me)(n-Hex)] 2(RBu或Ph)已被通过将甲基氯化镁与卤化锡偶合或通过锡酸锂与光学活性(2-辛基)甲苯磺酸酯的反应制备。两种方法的立体特异性都很高,从而导致了新的光学纯有机锡试剂已被充分表征。
