摘　　要：of main obsevation and conclusion 1,3-Dipolar aycloaddition reaction between organic azide and metal carbyne is a useful strategy to con-struct metallacycles.However,the electronic behavior of organic azide in 1,3-dipolar aycloaddition reactions is less explored.Tthis work revealed theunexpected role of organic azide as electrophiles in its cycloaditions with various metal carbynes.The feasility and regioselectivity of a Fischer-typeosmiun carbyne in its reaction with an organic azide are explained by the increased nucleophilicity of carbyne carbon upon bending.
