The deoxygenation of a few diaryl-phenylphosphine oxides, dimethyl-phenylphosphine oxide, and 3-methyl-1-phenyl-3-phospholene 1-oxide was studied by phenylsilane, tetramethyldisiloxane (TMDS), and polymethylhydrosiloxane (PMHS) under conventional or microwave (MW) heating, in toluene or in the absence of any solvent at different temperatures. It was found that the deoxygenation with TMDS or PMHS under

The deprotonation of 1-phenyl-3-phospholene I-oxide. I-sulfide or I-borane with I or 2 equiv of LDA, followed by quenching, with electrophiles gave a range of 2-mono- or 2.5-disubstituted phospholene derivatives in good yield. Only trans substitution in relation to the P-Ph group was observed. Treatment of lithiated phospholene intermediates with 1,3-dihaloalkanes afforded annulated 2-phenyl-2phosphabicyclo[3.3.0]oct-3-ene derivatives. The annulation reactions occurred with high regio- and stereoselectivity and led to the exclusive formation of the exo-Ph-P substituted products. (C) 2004 Elsevier Ltd. All rights reserved.
