Cadmium dimethyl, decomposition

Decomposition of dimethyl cadmium, Cd(CH3)2, at 10 Torr with argon laser. 

The decomposition of dimethyl cadmium in a toluene or benzene carrier system proceeds by the consecutive release of both methyl radicals57,58. The suggested mechanism is... 

Laurie and Long59 studied the thermal decomposition of dimethyl cadmium in the absence of inhibitors. Rate coefficients were calculated on the basis of the undecomposed alkyl. A marked surface affect was noted. The homogeneous rate coefficient was obtained at 258 °C by studying the pyrolysis with various surface to volume ratios and extrapolating to zero surface. The mechanism proposed is... 

CdSe is a compound II-VI semiconductor composed of Cd + and Se ions. In the original synthetic procedure described by the Bawendi group, dimethyl cadmium [(Me)2Cd] and tri-n-octylphosphine selenide (TOPSe) were used as the precursors for Cd and Se, respectively. Later, other cadmium compounds such as cadmium acetate [Cd(Ac)2] and CdO were used alternatively, because (Me)2Cd is extremely toxic and pyrophoric. Although the exact reaction pathway has not been clearly elucidated, it is thought that atoms of Cd and Se are released via the thermal decomposition of the precursors.
