facile one-pot synthesis of the 1,2-azaphospholanes by intramolecular alkylation of 3-halopropyl amides of tricoordinate phosphorus has been suggested. Using this method, a series of the differently N-substituted 1,2-azaphospholanium salts were synthesized. 3-Aminopropylphosphine oxides were obtained by hydrolysis of the salts. A probable mechanism of the 1,2-azaphospholanium salts formation is discussed
Photoinduced hydrophosphinylation of alkenes with diphenylphosphine oxide took place regioselectively affording the corresponding phosphine oxide in good yields. This hydrophosphinylation is of simple operation and widely tolerant to a variety of the functionalities. (C) 2008 Elsevier Ltd. All rights reserved.
