Abstract
The dichloride (I) is esterified with phenol (II) to give the phosphonate (III) which is reduced, forming the α-dichlorophosphine (IV).
ChemInform Abstract
The dichloride (I) is esterified with phenol (II) to give the phosphonate (III) which is reduced, forming the α-dichlorophosphine (IV). The intermediate C-chlorophosphaethylene, generated by treatment of (IV) with pyridine, is trapped with ethanethiol (V), 2,3-dimethylbuta-1,3-diene (VIII), or benzonitrile oxide (XI) to yield the phospha heterocycles (VI), (VII), (IX), (X), and (XII).
