摘要
Three types of reactions with organomanganate have been examined. The first topic is a reaction of gem-dibromo compounds such as gem-dibromocyclopropane and dibromomethyltrialkylsilane with trialkylmanganates(II). The reaction was initiated by bromine-manganese exchange. The second reaction is a radical cyclization of iodophenyl allyl ether and 2-iodoethanal acetal by means of trialkylmanganate(II). The third topic is an addition of allylmanganate to a carbon-carbon triple bond. A catalytic version of these reactions is also disclosed. (C) 1999 Elsevier Science S.A. All rights reserved.
