专利号:US-5463131-A 优先权日:1994-06-30 标题 :Synthesis of organohaloboranes and alkoxyorganoboranes 发明人:BURKHARDT ELIZABETH R 权利人:MINE SAFETY APPLIANCES CO 摘要:A one-step process is provided for the synthesis of organohaloboranes, including diisopinocampheylchloroborane, and alkoxyorganoboranes. The present process does not utilize a thermally unstable ether adduct or a malodorous dimethyl sulfide adduct as required in prior processes. In general, the organohaloboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with boron trihalide and diborane. Alkoxyorganoboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with alkylborate and diborane.
