Abstract : This invention relates to a new class of nitrogen-phosphorus heterocycles characterized by improved high-temperature anti-oxidant and wear resistant properties rendering them particularly adaptable for use as additives to lubricating oils, greases and hydraulic fluids. 5-Lower-alkyl-10-phenyl-5,10-dihydrophenophosphazine compounds are made by metalating a N-alkyl-2,2'-dihalodiphenylamine with magnesium or lithium and subsequently reacting the diorganometallic compound with phenyl- or alkyl-dihalophosphine.
