Abstract

Abstract This invention (A) relates to a process for producing at preferably low reaction temperatures, a triazine at high levels of conversion and yield from a haloalkane nitrile such as perfluoroalkane nitrile by the novel employment of a catalytic amount of a member selected from the group consisting of (1) an organic amine oxide, (2) an organic amine oxide hydrochloride of said organic amine oxide, and mixtures thereof, and (3) an organometallic catalyst selected from the group consisting of (a) an organometallic compound containing at least one metal-tocarbon bond in which said metal is selected from the group consisting of metals of the Periodic Table Groups IIIB, IVB, VB, VIB, VIIB, VIII, IB, IIB, a group VA metal having an atomic weight of at least about 30, and a Group IVA metal, and (b) a metal or metalloxy beta-ketoenolate of the formula: IN WHICH N IS AN INTEGER EQUAL TO THE VALENCE OF THE METAL OR METALLOXY ION, AND IN WHICH EACH OF R1, R2, and R3 is selected from the group consisting of hydrogen and an organic substituent, and in which R2 additionally includes halogen, nitro or sulfo, and also (B) relates to the novel employment of the above described catalyst in a catalytic amount employed with a polymer or copolymer containing at least greater than an average of one cyanohaloalkyl group per molecule of the polymer or copolymer, to form a cross-linked polymer or copolymer.
