Abstract:
CYCLIC COMPOUNDS HAVING ONE OF THE FOLLOWING FORMULAS: OR ARE DESCRIBED, WHERE N IS AN INTEGER NOT LESS THAN 4, AND THE UNSATURATIONS OF SAID COMPOUNDS EXHIBIT TRANS CONFIGURATIONS. THESES COMPOUNDS ARE PRODUCED BY A PROCESS COMPRISING REACTING BUTADIENE IN THE PRESENCE OF BOTH A NICKEL-HYDROGEN COORDINATION COMPLEX AND A HALOGENATED NICKEL-HYDROCARBON COORDINATION COMPLEX.
Abstract:
A compound represented by the general formula WHEREIN X and Y each represent an electron attracting group and Z represents a hydrogen atom, a mono-valent hydrocarbon radical, a di-valent hydrocarbon radical bonded to X or Y, or an alkadienyl radical represented by the formula -CH2-CH=CHCH2CH2CH2CH=CH2 or alkyl-substituted derivatives thereof, and a process for preparing said compounds by adding a 1,3-diene to an active methylene compound or hydrocarbon-substituted methylene compound having the electron attracting groups X and Y as represented by the general formula X - CH(Z) - Y, wherein X, Y and Z have the same meaning as above, using a palladium compound or a platinum compound as catalyst.
Abstract:
5-CYCLOHEXADECEN-1-ON IS PREPARED IN A HIGH YIELD BY HEAT TREATING 1,2-DIVINYL-CYCLODODECAN-1-OL IN THE PRESENCE OF N,Ndialkyl carboxylic acid amide, N-alkyl lactam or sulfoxide.
