    One co-ordinate phosphorus compounds : 1,3-dipolar cycloadditions with 2,2-dimethylpropylidynylphosphine
    (1984) Ko, Yeung Y. C. Yeung Lam; Carrié, Robert; Münch, Angelika; Becker, Gerd
    1,3-Dipolar cycloadditions of azides, p-chlorobenzonitrile oxide and methyl diazoacetate with 2,2-dimethylprophlidynylphosphine occur regiospecifically yielding cyclic ‘aromatic’ monoadducts: triaza-, oxaza-, and diaza- phospholes and the oxazaphosphole can react further with p-chlorobenzonitrile oxide to give a symmetrical [3.3.0] phosphorus heterocycle.
