cyclic vinylsilanes in a syn manner with NO+ bonding to the β-carbon and Cl− to the α-carbon, which is a reversal of the regiochemistry expected from the β-silicon effect. The adducts dimerize to a single diastereomer containing enantiomeric pairs and/or give secondary products on further reaction.
NOCl增加在环状乙烯基硅烷合成与NO方式+结合到β -碳和Cl -的α碳,这是从β-硅效果预期区域化学的逆转。加合物二聚成一个含有对映异构体对的单一非对映异构体,和/或在进一步反应时得到副产物。
