The reactivities of β‐amino‐α,β‐unsaturated Fischer carbenes of Cr(0) in the production of β‐amino‐1‐azadiene scaffolds were investigated. These complexes, functionalized with β‐donor groups, underwent a transmetalation process with copper catalysts as key intermediates, leading to the suggesting of a probable mechanism of reaction. The obtained azadienes were used for the syntheses of difluorodiazaborinines
研究了β-氨基-1-氮杂二烯支架中Cr(0)的β-氨基-α,β-不饱和Fischer卡宾的反应性。这些被β-给体基团官能化的配合物经历了以铜催化剂为主要中间体的金属转移过程,从而提示了可能的反应机理。所获得的氮杂二烯被用于二氟二氮杂硼烷酮的合成,其被寻找为荧光材料。
