Ni-Catalyzed C-P Coupling of Aryl, Benzyl, or Allyl Ammonium Salts with P(O)H Compounds

A methodology that allows for the construction of C-P bonds via the nickel-catalyzed cross-coupling of organoammonium salts with appropriate phosphorus nucleophiles has been developed. Aryl-, pyridyl-, benzyl-, and allyl-ammonium triflates can be employed as the electrophiles. The employed phosphorus-based nucleophiles included diaryl/dibutyl phosphine oxide, dialkyl phosphonates, and ethyl phenylphosphinate. Functional groups OMe, CN, CF3, F, Cl, C(O)NMe2, and C(O)tBu were tolerated.

Phosphine oxide hydroxyaryl mixtures with novolac resins for co-curing epoxy resins

A mixture of hydroxyarylphosphine oxides comprising (a) a mono(hydroxyaryl)phosphine oxide, (b) a bis(hydroxyaryl)phosphine oxide, (c) a tris((hydroxyaryl)phosphine oxide, and, optionally (d) a tri- aryl, alkyl, or aralkyl-substituted phosphine oxide combined with a phenolic co-crosslinking composition is useful as a polyhtdroxy mixture for co-crosslinking an epoxy resin which also imparts flame resistance.
