Formation by Thermal Decomposition of PH-Containing Compounds

PH3 was found to be one of the volatile thermolysis products of the arylphosphonous acids RCgH4P(0)(OH)H with R = H or CH3 in chlorobenzene in sealed tubes at 200 to 220 C after 20 h [30]. Pyrolysis studies of /-C4H9PH2 and f-C4HgPH2, intended to investigate the possible use of these compounds as precursors in the OMVPE process, revealed that PH3 is one of the first decomposition products [33, 34]. [Pg.122]

The energetics of the decomposition of PHg [31] and CH2=PH3 [32] to give PH3 were evaluated by ab initio MO studies at different computational levels. [Pg.122]
