Reactions of alkenes with the recently discovered monochloroborane-methyl sulfide (H2BC1. SMe2), monobromoboranemethyl sulfide (H2BBr. SMe2), and monoiodoborane- methyl sulfide (H2BI. SMe2) were investigated in detail in order to establish their usefulness as hydroborating agents. H2BCl. SMe2 hydroborates alkenes rapidly and quantitatively at 25 “C. Simple distillation under low pressure affords pure bBC1. Similarly, the ...
