SYNTHESIS, STRUCTURES AND PROPERTIES OF N-(TRIHALOGERMYLMETHYL)-SUBSTITUTED AMIDES, LACTAMS AND IMIDES, THE DERIVATIVES OF THE 5-COORDINATEGERMANIUM

The formation of trichlorogermyl-substituted amides, lactams, and imid es occurs when 2Et2O . HGeCl3 is condensed with compounds possessing t he -NCH2Cl fragment and equally well when HGeCl3 interacts with compou nds containing -NCH2OH and -NCH2OSiMe3 groups. In some cases, the use of the latter is more advantageous from the preparative point of view, In compounds thus obtained, the germanium is five-coordinate due to t he coordination [GRAPHICS]
