The addition of phosphorous tribromide or thionyl chloride to compounds of the type R3SiCH2CD2OH (where R3 = Me3, PhMe2, Ph2Me or Ph3) gave rise to approximately the same proportion of the α-deuteriated product R3SiCH2CD2X and the β-deuteriated product R3SiCD2CH2X in all cases. Fragmentation accompanied the rearrangement, the yields of breakdown products R3SiX, decreased with successive phenyl substitution
将三溴化磷或亚硫酰氯添加到R 3 SiCH 2 CD 2 OH类型的化合物(其中R 3 = Me 3,PhMe 2,Ph 2 Me或Ph 3)中,得到的氘代α的比例大致相同乘积R 3 SICH 2 CD 2 X和β-氘代乘积R 3 SICD 2 CH 2 X在所有情况下。碎片伴随重排,分解产物的收率R 3SiX随硅上的连续苯基取代而降低,并且用(2-羟乙基-2,2- d 2)三苯基硅烷Ph 3 SiCH 2 CD 2 OH几乎没有观察到分解。
