Oxidative addition reactions of cyclodiphosph(III)azanes

Abstract

The ansa compound {[t-BuN)P]2[O-6-t-Bu-4-Me-C6H2]2CH2} (2) reacts with two mole equivalents of selenium to afford the bis(seleno) compound {[t-BuN)P(Se)]2[O-6-t-Bu-4-Me-C6,H2]2CH2} (3): under analogous conditions sulfur gives the P(III)-N-P(V) derivative {[(t-BuN)PN(t-Bu)P(S)][O-6-t-Bu-4-Me-C6H2]2CH2} (4). These reactions are compared with those using [(ArO)PN(t-Bu)]2 (5) and the macrocycle {[t-BuN-P]2(OCH2CMe2CH2O)}2(6).
