The preparation and characterisation of the Group IVA neopentyls (Me3CCH2)4M (M = Ti, Zr, or Hf) is described. Spectroscopic data (IR, Raman, mass, 1H NMR, and PE) are provided; IR and Raman bands have been assigned by comparison with results on Group IVB analogues (M = Ge or Sn). MC4 stretching vibrations fall in the range 540–485 cm−1, and bending modes at 240–283 cm−1. Thermal decomposition gives
描述了IVA族新戊基(Me 3 CCH 2)4 M(M = Ti,Zr或Hf)的制备和表征。提供了光谱数据(IR,拉曼,质量,1 H NMR和PE);通过与IVB组类似物(M = Ge或Sn)的结果进行比较,确定了IR和拉曼谱带。MC 4的拉伸振动在540–485 cm -1的范围内,弯曲模式在240–283 cm -1的范围内。热分解产生
