BiX3 as an efficient and selective reagent for the halogen exchange reaction
Bismuth halides are efficient and selective reagents in the halogen exchange reactions carried out under mild conditions. This rapid, high yield reaction proceeds mainly with retention of configuration.

COMPETITION BETWEEN n,?- AND n,?-ORBITAL INTERACTIONS IN CHLORINATED ETHERS R-O-CHClR1
Using the AM-1 method, we have studied CH2=CH-O-CHClR1 molecules (R1 = H, Me).We have shown that the sc conformation with respect to the Csp3-O bond is preferred.We have systematized the 35Cl NOR data on the degree of manifestation of the generalized anomeric effect in R-OCHClR1 2C(=O)> molecules.We have established that enhancement of n,? conjugation in the R-O fragment leads to weakening of the n,? interaction in the O-C-Cl triad.
