Ring opening metathesis polymerization (ROMP) of dicyclopentadiene (DCPD) catalyzed by titanium tetrachloride adduct complexes such as TiCl 4 β 2L [L Ο pyridine (1), 2-methylpyridine (2), 2,4,6-trimethylpyridine (3), 3-aminopyridine (4), 2-hyroxypyridine (5)] and CH 3 Li as cocatalyst was reported.
The CD spectra of several 3-substituted azido-, amino-, thio-, phenylseleno-and (phosphonoseleno)-b,bcarotene derivatives with one or two stereogenic centers are discussed with respect to conformational changes of the cyclohexene end group. N-and S-Substituents (N 3 , NH 2 , SH) have no influence on
Palladium-catalyzed cyclizations of the 2-bromo-1,6-diene 6 57 with a methoxycarbonyloxymethylene substituent on the triple bond gave in 36% yield the 2,3-bis(bicyclo[3.1.0]hex-with an acetoxymethyl substituent on the bromoalkenyl moiety did not only lead to the expected 1-acetoxymethyl-1-yl)-substi
