REDUCTIVE CLEAVAGE OF THE HALOGEN-PHOSPHORUS, OXYGEN-PHOSPHORUS AND PHOSPHORUS-PHOSPHORUS BONDS WITH ALKALI METALS
摘要:
The reduction of phosphorus acid chlorides as well as hypophosphates, pyrophosphates and mixed P(III)-P(V) anhydrides with alkali metals (Li, Na, K) in NH3 liq. / THF solution and potassium naphthalenide was investigated. It was found that this type of phosphorus compounds easily undergo reduction: a) >P(O)Cl to >P(O)H; b) >P(O)P(O)< to >P(O)H; C) >P(O)-O-P(O)< to >P(O)OH and >P(O)H; d) >P(O)-O-P< to >P(O)O- and >P-. The results of our experiments strongly suggest that the mixed P(III)-P(V) anhydride is reduced by potassium naphthalenide in THF with the cleavage of the P(III) - oxygen bond.

It has been shown that the reaction of Grignardreagents containing tertiary aliphatic radicals with phosphonicdichlorides may yield as many as four products, depending on the nature of the reactants. Some of these products are described for the first time.
