Phenylphosphonic dichloride → HCID 13037499, compound

Participants

Reaction Steps

The procedure of Example 1 was employed utilizing N-t-butyl-N-benzylamine and phenyl phosphonic dichloride. The reaction of the dilithio compound and the phenyl phosphonic dichloride was conducted at 0° C. The crude product produced as a result of the chromatographic separation was distilled at 160° C. and 0.2 mm to yield a colorless oil. The colorless oil was slurried in petroleum ether to yield 1-phenyl-2-(t-butyl)-2,3-dihydro-1H-2,1-benzazaphosphole-1-oxide (2.75 g, 16% yield) as a white solid having a melting point of 89°-91° C. and the following analysis:
