[摘要]:Heavier group 2 (Mg, Ca) bis(trimethylsilyl)amides are catalysts for the formation of unsymmetrical diaminoboranes, [(R2N)BH(NR'(2))], by dehydrocoupling of amine boranes and protic amines; a process which is proposed to occur by a sequential metal-centred elimination-insertion-elimination mechanism. |
