摘要：

The xanthate of a hindered secondary alcohol can be deoxygenated easily with phosphine-boranes and AIBN in a high yielding radical chain reaction. A similar efficient olefin forming reaction has been seen with a 1,2-dixanthate under the same conditions. In contrast to tin hydride based reagents phosphine-boranes do not reduce chlorides or bromides. (C) 1998 Elsevier Science Ltd. All rights reserved.
