General description

Boron trichloride (BCl3) is a boron halide typically used as a reagent in organic synthesis for the cleavage of C-O bonds in ethers.

Application

Boron trichloride (BCl3) can be used as a reactant in the preperation of borazine-linked polymer [BLP-10(Cl)] by thermal decomposition with benzidine for gas storage and purification.

A general method to prepare a new class of carbohydrate-derived, enantiomerically pure polyhydroxypyrroline N-oxides from their alkoxy (protected) derivatives is presented. Boron trichloride is shown to cleave efficiently benzyl ethers and ketals without affecting the imine N-oxide functionality of nitrones.

Sky-blue Tp*WOCl(2) has been synthesized from the high-yielding reaction of Tp*WO(2)Cl with boron trichloride in refluxing toluene. Dark-red Tp*WOI(2) was prepared via thermal decarbonylation followed by aerial oxidation of Tp*WI(CO)(3) in acetonitrile. From these precursors, an extensive series of mononuclear
