Ranks ( nucleofugalities) of Br, Cl, OSO2C6H4Me, SO2Ph, SPh, and Oph as leaving groups in sulphonyl-activated cyclopropane-forming eliminations have been determined; a rectilinear correlation between rank and the pka of the conjugate acid of the leaving group is found in direct contrast with behaviour in alkene-forming elimination.
确定了在磺酰基活化的环丙烷形成消除反应中作为离去基团的Br,Cl,OSO 2 C 6 H 4 Me,SO 2 Ph,SPh和Oph的等级(核功能);发现等级与离去基团的共轭酸的p k a之间的直线相关性与形成烯烃的消除的行为直接相反。
