Comparison of nucleofugalities in 1, 2- and 1, 3-elimination reactions
Abstract
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.
