Very‐low‐pressure pyrolysis (VLPP) of group IV (A) tetramethyls: Neopentane and tetramethyltin

The decomposition of neopentane was studied using the very‐low‐pressure pyrolysis (VLPP) technique at temperatures from 1000 to 1260 K. The derived Arrhenius parameters are consistent with δ H f 0 ( t ‐butyl) = 8.4 kcal/mol. Using the above A factor, data on the decomposition of tetramethyltin yield DH 0 (Sn(CH 3 ) 3 ‐ CH 3 ) = 69 ± 2 kcal/mol.
