Some other interesting copolymers having properties of PVC thermal stabUizers, like poly[Af-(a-benzothiazolonylmethyl)methacrylate-co-methyl methacrylate] [45], of flame retardants like a terpolymer of styrene, acrylonitrile and a polymerizable perbrominated phenol [76] or poly[4-methacryloyloxy-2,3,5,6-tetrabromobenzyldi-phenyl phosphonate-co-methyl methacrylate] [104] (93), bioddes, mostly copolymers of monomers containing tris(n-butyl tin) or triphenyl tin moieties and alkyl acrylates, methacrylates, vinyl acetate, acrylonitrile, styrene or A-vinylpyrrolidone [105], e.g. a terpolymer of styrene, MMA and tri(n-butyl tin) itaconate [106] (94),... 

The ylidic l-phenylimino-2,4,5-triphenyl-l,2,3-triazole (411) cf. Section 4.11.4.6) has been shown to be an effective 1,3-dipolar system which can be reacted smoothly with CS2, PhNCS, alkynic esters, ethyl acrylate and acrylonitrile to give [3 + 2] cycloadducts, e.g. (412). Upon photolysis or thermolysis the 2,4,5-triphenyl-2if-triazole (413) is formed... 

Dieb-Alder catalyst. The complex (1) catalyzes the homo-Diels-Alder condensation of vinyl compounds to norbomadicne. Thus the reaction of acrylonitrile with norbornadiene in the presence of this complex gives 8-cyanotetracyclo[4.3.0.0. 0 -nonane (2) as a mixture of epimers in 93 % yield. The yield of (2) using bis(triphenyl-phosphine)dicarbonylnickel(O) as catalyst is 86%.

Irradiation of phenyl-2//-azirines in the presence of carbon dioxide leads to the formation of the 3-oxazoline-5-one system121-123 and, in some cases, to the isomeric 2-oxazolin-5-one122 [Eq. (24)1. The azirines serve as incipient nitrile ylides, whose 1,3-dipolar structure permits cycloaddition to the dipolarophile C02123 [Eq. (25)1. The reverse reaction, photolytic extrusion of C02 from pseudoxazolones, is synthetically useful, since the dipolar nitrile ylide thus formed can be trapped with a variety of dipolarophiles. Thus, 2,2,4-triphenyl-3-oxazolin-5-one (48) is readily converted into the stabilized ylide (49)124 [Eq. (26)1, and the use of methyl acrylate,122 acrylonitrile,122 and dimethylacetylene dicarboxy-... 

Acrylonitrile also undergoes dimerization to afford trans-fu td cyclobutanes by using ethylene-Z w-triphenyl phosphine nickel or Z /5 -triphenylphosphine nickelacyclopentane as catalysts Dimers are obtained on irradiation (A, > 400 nm) of the crystalline stilbene derivative 259, which at room temperature yields the (2 + 2)-cycloadduct 260. Oligomers are also produced from this reaction. The reactivity is temperature dependent, however, and irradiation at -78°C using X > 300 nm yields the double (2 + 2)-product 261 in 27% yield. Interestingly, the cycloadducts are formed only by cyanoalkene-alkene interactions. A re-investigation of the solid-phase dimerization of 262 has identified 263 as the...

The complex (CH2=CHCN)3Mo(CO)3 is known and in this case the acrylonitrile is bonding as a 2-electron C=C system [88]. With nickel tetra-carbonyl, acrylonitrile forms the pyrophoric deep red (CH2=CHCN)2Ni [91], whose structure is unknown [85]. Treatment of this with triphenyl-phosphine gives the complex (PPh3)2Ni(CH2=CHCN)2 two possible structures for which are (A) and (B).
