The discovery of junipal focused the attention of Sorensen, who had been investigating the occurrence of polyacetylenes in Com-positae, on the possibility that these acetylenes were accompanied by thiophenes. From Coreopsis grandiflora Hogg ex sweet, 2-phenyl 5-(1-propynyl) thiophene (240) was isolated and its structure confirmed by synthesis of the tetrahydro compound, 2-phenyl-5-n-propyl-thiophene. From the root of tansy, the cis and trans isomers of methyl 5-(l-propynyl)-2-thienylacrylate (241) have been isolated. The total synthesis of trans (241) was achieved by reacting junipal with methylcarbethoxy triphenylphosphonium bromide (Wittig reaction) Several monosubstituted thiophenes, (242), (243), and... 

In contrast with irradiation of ACSO and PCSO, where volatile products were formed (sulfides, disulfides and alcohols), no volatile products were formed in the radiolysis of aqueous solutions of S-(cis- l-propenyl)-L-cysteine. Here the authors found that reactions of OH" radicals are responsible for the formation of propyl-1-propenyl sulfides (cis and trans).

Bei der Hydroaluminierung von Alkinen tritt die Oligomerisierung oft bereits bei nied-rigeren Temperaturen in den Vordergrund. So erhalt man z.B. aus 3,3-Dimethyl-l-phe-nyl-butin (I) und Bis-[2-methyl-propyl]-aluminiumhydrid (1 1) bei 50° 94% d.Th. cis-3,3-Dimethyl-l-phenyl-buten-(l) (II)5 neben 6% d.Th. trans,trans-2,2,7,7-Tetramethyl-4,5-diphenyl-octadien-(3,5) (III) ... 

To determine the potentiality of catalyst 72a, various alkenes with methyl, ethyl and iso-propyl substituents in cis or trans orientations relative to the aryl substituent were hydrogenated (Scheme 47). In general, (E)-alkenes produced better results than their cis isomers.

Irradiation of acetone or methanol solutions of this compound at — 50°C, however, yields the cis photoisomer, which upon warming (0°C), decomposes to yield photoelimination products. This is taken as evidence that the major path at room temperature involves photoisomerization of the trans to cis isomer and rapid thermolysis of the latter. Similar behavior was observed for azobis(isobutyronitrile), azobis(cyanocyclohexane), and azobis(2-methyl-propyl acetate).(4>...
