Novel substituted cyclophosphate compounds of the formula: WHEREIN X is halogen, hydrocarbyl, sulfhydryl, thioether, alkylsulfoxy, alkylsulfonyl or hydrocarbyl-substituted amino wherein said hydrocarbyl and alkyl radicals contain up to about 12 carbon atoms, and R3 is hydrogen or hydroxyl; ARE PREPARED BY REACTING THE CORRESPONDING AMINE COMPOUND (WHEREIN X in the formula is NH2) with a nitrite and haloboric acid at a temperature below 0*C. to yield a compound wherein X in the formula is halogen, and converting the halogen compound, if desired, to one in which X has the other definitions set forth above, in conventional manner. Alternatively, the novel compounds are prepared from open-ring diamine compounds by reacting with an alkali metal xanthogenate or an orthoformate. |
