Abstract

Abstract Nucleophilic substitution of 1, 3-diiodobicyclo [1.1. 1] pentane by tertiary amines and pyridines was investigated. The structure of cage quaternary salts obtained together with the observation of the competitive addition of pyridine in the reaction of [1.1. 1] propellane with iodine indicate the existence of a relatively stable “hot intermediate” very close in its structure to a stabilized 3-iodo-1-bicyclo [1.1. 1] pentyl cation.
