Synthesis and photochromic properties of tetrakis(3,5-dimethyl-2-thienyl)- and tetrakis(2,5-dimethyl-3-thienyl)ethylenes

Tetrakis(3,5-dimethyl-2-thienyl)ethylene and tetrakis(2,5-dimethyl-3- thienyl)ethylene were obtained from the corresponding dithienyl ketones by the McMurry reaction. The photochromic properties of the compounds obtained were studied.

Effects of base, electrophile, and substrate on the selective alkylation of heteroaromatic systems

Several heteroaromatic systems, including oxazoles, pyrazoles, and thiophenes, are regioselectively alkylated using lithium diethylamide. Effects of substrate, base, and electrophile on the selectivity of this process are surveyed and interpreted.

Regioselective Synthesis of 2-Functionalized Thiophenes by Condensation of α-Mercapto Compounds with β-Aminoenone Derivatives

2-Acylthiophenes and ethyl 2-thiophenecarboxylates are prepared regioselectively by reaction of 3-chloroenones and 2-acylenammonium chlorides with α-mercapto derivatives in good to moderate yields.
