1-dichlorophosphorylethane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a manner similar to that of Example 1, 2-ethyl-2-propanethiol was reacted with ethylphosphonic dichloride to obtain the title compound.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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: was conducted at -76° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a manner similar to that of Example 1, 2-ethyl-2-propanethiol was reacted with ethylphosphonic dichloride to obtain the title compound.
