(2,2-Dimethylpropylidyne)phosphane (7) undergoes regiospecific -cycloaddition reactions with the arylnitrile oxides 2a-c to yield the 1,2,4-oxazaphospholes 8a-c.In the reaction of phosphaalkyne 7 with 2,2-dimethylpropanenitrile oxide (2d) the 1:2-adduct 10 is formed in addition to 8d.The reaction of 7 with the nitrile sulphide 12 produces the 1,2,4-thiazaphosphole 13.The 1H-1,2,4-diazaphospholes 18a-c are obtained from the reactions of 7 with the nitrile imines 17a-c; the regioisomers 21a and 21b have been detected by NMR spectroscopy.
