Cyclopymerization polymers from non-conjugated dienes

Novel homopolymer and copolymer compositions produced from the polymerization of non-conjugated dienes have been discovered. The novel compositions are produced by an equally novel process comprising cyclopolymerization of non-conjugated dienes employing reduced valence state Group VIB metal oxide catalyst on porous support. The preferred catalyst comprises carbon monoxide reduced chromium on silica. Copolymers are formed by copolymerization of non-conjugated dienes with 1-alkenes in contact with the activated chromium on silica catalyst. The compositions are useful as lubricants and additives.

The Heat of Formation of the Allyl and Methallyl Radical

The decomposition of 1,5-hexadiene (1), 2-methyl-1,5-hexadiene (7), and 2,5-dimethyl-1,5-hexadiene into allyl- (2) and methallyl radicals (6) was studied by means of the shoke tube technique with and without oxygen as scavenger.From these data and from the temperature dependence of the equilibria 1 2 and 5 6, measured between 600 and 800 deg C, the heat of formation of the allyl (2) and methallyl radical (6) as well as the activation parameters for the recombination and disproportionation of these radicals have been deduced.

THE REDUCTION OF 2-VINYL-1,1-BIS(BROMOMETHYL)CYCLOPROPANE

A study was carried out on the reduction of 2-vinyl-1,1-bis(bromomethyl)cyclopropane by various methods including electrochemical procedures.The major reaction pathways ential opening and expansion of the cyclopropane ring, while the product of the formation of a second three-membered ring, namely, vinylspiropentane, is formed in low yield.The probable radical mechanism for this reaction is discussed.

Reactions of Allylic Grignard Reagents and Unsaturated Amines

Reactions were studied of allylic Grignard reagents with allylic and propargylic amines.Additions were observed to N-allylaniline (1), cinnamylamine (6), N,N-dimethylcinnamylamine (10), and 3-(dimethylamino)-1-phenyl-1-propyne (12) but not to allylamine, diallylamine, N-allyl-N-methylaniline, N,N-dimethylallylamine, or N,N-diethylallylamine.Reactions of 3-amino-1-phenyl-1-propyne (8) furnished phenylacetylene rather than an addition product.By comparing reactivities of the amines and comparablehydrocarbons, it is concluded that tertiary amino functions and metalated primary and secondary amino functions can assist Grignard reagent additions to alkene and alkyne functions.Comparisons of reactivities of theunsaturated amines and comparable alcohols suggest that assistance by a metalated amino function is less effective than by a metalated hydroxyl function but more effective than by a tertiary amino function.Another comparison suggests that a metalated phenylamino group is more effective than a metalated primary amino group.
