Yields and Stereoselectivities of Chlorinolysis of Trialkylboranes. Comparison of a Variety of Selected Methods Donna J. Nelson* and Raman Soundararajan Department of Chemistry, University of Oklahoma, Norman, Oklahoma 73019
Received April 29, 1988 Yields and stereoselectivitiesfor chlorinolysis of a series of representative trialkylboranes R3B (R = pentyl, hexyl, cyclohexyl, sec-butyl, ezo-2-norbornyl)with a variety of chlorinolysis methods (CuC12/H20;FeC1,; dichloramine T; NCl,; t-BuOC1) are compared. Of the easily handled reagents, dichloramine T generalIy gives good yields and is most stereoselective(>99% exo-:99:99:99:
