    • 1,214,513. Dimerizing dienes; cyclobulane derivatives. STUDIENGESELLSCHAFT KOHLE m.b.H. 27 March, 1968 [8 April, 1967], No. 14628/68. Heading C5E. 1,3 - Dienes are cylodimerized by contact with a catalyst prepared by either (1) mixing a reducible nickel compound with an electron donor and a metal, metal hydride or halogenfree organometallic compound, having in each case a reducing action on the nickel compound, or (2) mixing a nickel complex compound containing zero-valent nickel with an electron donor. The cyclodimerization is conducted under conditions resulting in incomplete conversion of the diene. Suitable catalysts are formed from these components: nickel acetylacetonate / diethyl aluminium ethoxyl / tri- (o - phenyl - phenyl) phosphite (i.e. type 1), and bis (cyclooctadienyl) nickel / tri - (o - phenylphenyl) phosphite (i.e. type 2). In examples: (1-5, 8, 11 - 12) butadiene yields mainly cis-divinylcyclobutane and cyclooctadiene; (6 and 7) butadiene yields the same plus 4-vinylcyclohexene; (9) piperylene yields mainly dimethylcyclooctadiene and a mixture of the novel compounds 1,2 - cis - divinyl - 3,4 - dimethylcyclobutane and 1 - propenyl - 2 - vinyl- 3 - methyl - cyclobutane; and (10) a butadiene/ 2-butyne mixture yields mainly cis-divinylcyclobutane, cyclooctadiene, and dimethylcyclodecatriene.

The invention comprises trans-1-vinyl-2-cispropenyl-3-methyl-cyclobutane, trans-1-vinyl- 2 - trans - propenyl - 3 - methyl - cyclobutane and 1,2 - dipropenyl - 3,4 - dimethyl - cyclobutane. These compounds are prepared by the irradiation with ultraviolet light of 2,4-hexadiene and 1,3 - butadiene in mol. ratios 1À5 : 1 to 1 : 1.5 or 2,4 - hexadiene alone (as appropriate) in an inert atmosphere at- 20‹ to + 30‹ C. in the presence of a carbonyl compound as sensitizer. Sensitizers specified are acetophenone, benzil, benzanthrone, anthraquinone, p,p 1 - tetramethyl - aminobenzophenone, 1- acetonaphthone, 2-acetonaphthone, benzophenone and 2 - naphthaldehyde. The process may be carried out in the presence of an alkane or cycloalkane.

    • Vinyl-alkenyl-cyclobutanes of the formula in which each R is H or CH3 provided at least one R is H and at least one R is CH3, are obtained by codimerizing butadiene with a C5 or C6 conjugated diene at -20 DEG to +20 DEG C. with ultraviolet radiation in the presence of a sensitizer. The conjugated diene may be isoprene which gives trans - 1,2 - divinyl - 1 - methylcyclo-butane and trans-1-isopropenyl-2-vinylcyclo-butane, piperylene which gives trans-1-propenyl - 2 - vinylcyclobutane or 2,3-dimethyl-butadiene which gives trans-1-methyl-1-isopropenyl-2-vinylcyclobutane, and is used in a molar ratio to butadiene of 1: 1 to 1.5: 5. The sensitizer is a carbonyl compound.ALSO:Vinylalkenylcyclobutanes of the formula in which each R is H or CH3 provided at least one is H and at least one is CH3, can be homopolymerized or copolymerized e.g. to form a terpolymer with ethylene and propylene which is vulcanizable with sulphur and accelerators.
