Contributions to the Chemistry of Boron. 114. Evaluation of Substitution Reactions by 10B Isotopic Labeling: Reactions of Trithiadiborolanes Y2B2S3 with Borane(3) Derivatives BX3

Reactions between trithiadiborolanes Y2B2S3 and boranes BX3 are characterized by an exocyclic substituent exchange Y vs.X, and by an endocyclic process proceeding via ring opening and BY vs.BX exchange. 10B isotopic labeling distinguishes between the two routes.The exo-reaction dominates if the substituents at the trithiadiborolanes are more basic than the ring sulfur atoms, the endo-reaction if the substituents at the ring carry no lone pair of electrons, e.g.CH3.Steric effects influence the ratio of the exo:endo-reactions.Intermediates, probably ring opened, can be detected by 11B NMR, they are stabilized especially by dimethylamino groups.
