“…Since the halogenated species have a high dipole moment and magnetic sensitivity, line broadening occurs. A detailed spectral study of chloro and bromo analogues of 2,2dihalo-1-propylcyclopropanecarboxylic acids and 1,1-dihalo-2phenyl cyclopropane derivatives was reported by Sydnes et al 64 They also investigated the photochemical debromination products via a detailed 1 H NMR study of the mono brominated products. The structural analysis of polyfunctionalized gemdihalocyclopropanes was carried out by using X-ray diffraction and the absolute configuration (1′S, 3R) was established by refinement of the Flack parameter.…”

gem-Dihalocyclopropanes have wide-spread applications in organic synthesis due to their versatile chemistry. They can serve as substrates for a large range of useful materials such as natural products, alkaloids, cyclopropanes, heterocycles, aromatic ring systems etc. Normally the dihalocyclopropanes are prepared by the addition of dihalocarbene to alkene, but due to the great synthetic efficacy of gem-dihalocyclopropanes a number of methods have been developed for their synthesis. Generally gem-dihalocyclopropanes exist as strained cyclic systems with astonishing kinetic stability. They are capable of undergoing transformations leading to a variety of products which have potential applications in various synthetic organic chemistry fields.
