The general dehalogenation of alkyl halides with zinc using D2O or H2O as a deuterium or hydrogen donor has been developed. The method provides an efficient and economic protocol for deuterium-labeled derivatives with a wide substrate scope under mild reaction conditions. Mechanistic studies indicated that a radical process is involved for the formation of organozinc intermediates. The facile hydrolysis of the organozinc intermediates provides the driving force for this transformation.

The treatment of various 1,3-dihalides including the ones bearing an ester group with the titanocene(II) species produced cyclopropanes in good yields. The reaction of dihalides possessing two secondary halogens proceeded stereoselectively to afford trans
