Synthesis of nitrido(phthalocyaninato)metal(V) complexes RnPcMN (M = Re, Mo, W) and new compounds with nitrido-bridges between rhenium and elements of the third main group

摘要

New tetra- and octasubstituted nitrido(phthalocyaninato)metal(V) complexes RnPcMN (M = Re, Mo, W) were synthesized to obtain soluble nitrido-bridged phthalocyanines. Phthalocyanines with nitrido bridges between rhenium and boron, aluminium, gallium and indium, respectively, were synthesized from nitrido(tetra-tert. -butylphthalocyaninato)rhenium(V) complex, tBu(4)PcReN and suitable electrophilic reagents like BCl3, B(C6F5)(3), BPh3, BEt3, AlCl3, GaCl3, GaBr3, InCl3, etc. The nitrido-bridged compounds prepared show different stabilities depending on the substituents at the boron atom. Additionally, the possibility to increase the nucleophilicity of (C5H11)(8)PcWN by reducing this complex with C8K was studied. The reaction of the reduced complex with electrophiles, e.g. with tBuMeSiCl, Ph3SiCl and Me3GeCl indicates the formation of nitrogen-bridged complexes. [References: 78]
