摘要
本文报道(N,N-二烃基胺基)二氯硼烷的反常三烃化反应。2-苯并噻唑基Grignard剂与(N,N-二乙胺基)二氯硼烷反应,得到二乙胺合三(2-苯并嚷唑基)硼烷,并讨论了反应机理。分子结构经X单晶结构分析确证。晶体结构属正交晶系,空间群为P2_12_12_1,晶胞参数a=11.570(3),b=12.496(4),c=16.577(4)nm;Z=4,V=2397.3nm^3,D_0=1.348g/cm^3,μ(MoK_a)=3.167cm^(-1)。
Reaction of 2-Benzothiazolylmagnesium bromide with (N, N-dtethylamino) dichloroborane took place with trisheteroarylation instead of dihe beroarylation at the boron atom, and tris (2-benzothiazolyl) borane was isolated as its diethylamine adduct. The molecular structure of which was confirmed by X-ray crystallographic analysis. The crystal belongs to orthorhombic, space group P2_12_12_1, with a=11.570(3), b=12.496(4), c=16.577(4)nm; Z=4 and D_c=1.348 g/cm^3
