Studies of the Oxidation of Elemental Phosphorus by Substituted ortho-Benzoquinones
Annan, Theodore A.,Tian, Zhigang,Tuck, Dennis G.
, p. 19 - 22 (1991)
The phosphorus compounds P(O2C6R)2Br (R = Cl4, Br4 or Bu2H2) have been prepared by the reaction of P4, Br2 and the substituted o-benzoquinone RC6O2-o.There is no reaction between Bu2H2C6O2-o, P4 and Ph2Se2, but in the presence of catalytic quantities of B
