It has recently been shown that propane can be selectively ammoxidized to acrylonitrile using V-Sb-oxide based catalysts [3], but this catalyst is poor active and selective in the ammoxidation of ethane due to the different characteristics of C2 and C3 alkanes and their intermediates (for example, only primary H atoms are present in ethane and in the ethylene intermediate are absent allylic H atoms such as in propene).

In a related synthesis, bsa has been prepared by treating hexamethyldisilazane with ketene (Equation (193)) <62RTC430>. In a related study, the coordination chemistry of 1,1-dimethylurea in platinum(II)-dien complexes was also explored.165 Once again, both O- and N-bound linkage isomers were isolated and characterized, with the latter being slightly thermodynamically favored (Keq(N-isomer/O-isomer) ∼ 3).
