using the reaction with methyl iodide. Pinacol iodomethaneboronate reacts efficiently wit tertiary amines to form the crystalline quaternary ammonium salts. Dibutyl iodomethaneboronate reacts with excess piperidine or morpholine in ether to precipitate piperidine or morpholine hydriodide and yield the distillable piperidino- or morpholinomethaneboronic ester. Benzylamine failed to yield a stable product

sulfur. Under free radical conditions, α-(phenylthio)alkaneboronic esters are cleaved to α-(phenylthio)alkyl chlorides by either N-chlorosuccinimide or sulfuryl chloride. Pinacol phenylthio(triphenylstannyl)methaneboronate with sulfuryl chloride yielded (phenylthio)dichloromethane, without any evidence of selectivity between carbontin and carbonboron bond cleavage.
