WebThey are also obtained by alkali-metal reductive cleavage of triarylphosphines followed by hydrolysis of the resulting phosphide salt. The latter route is employed to prepare diphenylphosphine (Ph 2 PH). Diorganophosphinic acids, R 2 P (O)OH, can also be reduced with diisobutylaluminium hydride. WebPhosphine has an inhibitory effect on insect respiration and is unique in that it is only toxic to insects in the presence of oxygen - in the absence of oxygen it is not absorbed and is not toxic to insects (Bond et al 1967, 1969). However, the action of phosphine is potentiated by carbon dioxide and the exposure time
