T. Takahashi et al., OPTICALLY PURE HALOSELENURANES - FIRST SYNTHESIS AND NUCLEOPHILIC SUBSTITUTIONS, Journal of organic chemistry, 59(12), 1994, pp. 3262-3264
The first synthesis of optically pure haloselenuranes 1 has been accom
plished by utilizing the 2-exehydroxy-10-bornyl group as a chiral liga
nd. Complete retention of the configuration has been observed in inter
conversion reactions between haloselenuranes 1 and selenoxide 2 and in
nucleophilic substitution reactions of 1.
