Versuchsvorschrift
The procedure of Example 1 was employed utilizing N-benzylaniline and ethyl phosphonic dichloride. The reaction of the dilithio compound and the ethyl phosphonic dichloride was conducted at -76° C. to yield 1-ethyl-2-phenyl-2,3-dihydro-1H-2,1-benzazaphosphole-1-oxide (0.45 g, 6% yield) as a pale yellow solid having a melting point of 116°-120° C. and the following analysis:
