The first examples of the hydrophosphination of alkyl vinyl sulfides and selenides are described. The reaction of secondary phosphines (R 1 ) 2 PH 1-3 with vinyl chalcogenides CH 2 =CHXR 2 4-9 proceeds readily under radical initiation to give in anti-Markovnikov mode regiospecifically the corresponding organylchalcogenophosphines (R 1 ) 2 PCH 2 CH 2 XR 2 10a-h in high yields.

Addition reactions with complete atom economy conform to the “green chemistry” principles, and they constitute now a purposefully and dynamically developing field of organic chemistry [1–7]. Of particular interest are atom-economic processes that can be readily accomplished without catalyst and solvent [8–10]. In recent years, convenient methods for carbon–phosphorus bond formation via noncatalytic
