However, Me3Sn·NMe2 reacted with an excess of (I) to give 2,6-diphenyl-1,3,5-oxadiazin-4-one (XV) with evolution of carbon dioxide. The corresponding germanium compound showed behaviour intermediate between that of the analogous silicon and tin compounds.
结果表明,苯甲酰基异氰酸酯(I)可以插入N-三甲基金属(IV)二烷基胺(Me 3 M·NR 1 R 2; M = Si,Ge和Sn)的金属-氮键中;讨论了加合物的结构。当以2:1的摩尔比用Me 3 Si·NR 1 R 2处理(I)时,消除了苯甲酸三甲基甲硅烷基酯,并且2-二烷基氨基-6-苯基-1,3,5-恶二嗪-4-酮(VII)和分离出4,6-二苯基-1,3,5-恶二嗪-2-酮(XI)。(VII)和(XI)的产率受烷基取代基(R 1,R 2)影响。但是,我3 Sn·NMe 2与过量的(I)反应生成2,6-二苯基-1,3,5-恶二嗪-4-酮(XV),并释放出二氧化碳。相应的锗化合物表现出介于相似的硅和锡化合物之间的行为。
