Thermal decomposition of the dichloro-adducts derived from alpha-phenylselanylesters 1, 2 and 4 has been studied. N-Chloro-succinimide treatment of esters 2 was an efficient preparative method for alpha-chloro-alpha-phenylselanylesters 10 and alpha-chloro-alpha,beta-unsaturated esters 11. Some transformations of esters 10 were achieved. alpha,beta-Dichloro-alpha-phenylselanylesters 22 were prepared from beta-chloro-alpha-phenyl selanylesters 5 or by decomposition of the dichloroselenuranes 21 derived from esters 4.
