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.

A novel and efficient microwave-assisted, BCl(3) mediated coupling reaction to synthesize o-(hydroxyaryl)(aryl)methanone structures from phenols and acyl chlorides is described. This reaction was further incorporated into a two-step synthesis of biologically interesting xanthones.
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

The reactions of boron halides with free base porphyrins under conditions where partial hydrolysis of the boron halides can occur give diboron porphyrin complexes containing BOB moieties in which each boron is bonded to two porphyrin nitrogen atoms. BF(3).OEt(2) with

To examine whether semiconductor workers exposed to complex mixtures of chemical waste show an increase in genotoxic effects, and, if so, whether occupational safety measures protect these workers. To assess chemical exposure in the workplace, air monitoring of boron trifluoride
