Abstract: Abstract The reaction of N’-(aryl)benzothiohydrazides with 2-chloro-7-cyclopropyl-3-nitro-4-oxothieno[2,3-b]pyridine-5-carboxylic ester/acid in the presence of triethylamine furnished, upon addition of iodomethane, the respective 1,3,4-thiadiazoline-(6-methylthio-4-oxopyridine) hybrids. Interestingly, the reaction of thiohydrazides with 4-oxothieno[2,3-b]pyridines incorporating N1-(2’-halogeno-5’-nitrophenyl) entities generated 1,3-thiazoline ring… read more here.

Abstract: Two new Cu(I) dimers chelated with thiophene ring-introduced diphosphine ligands [Cu(μ2-I)dppt1]2 and [Cu(μ2-I)dppt2]2 (dppt1 = 3,4-bis(diphenylphosphino)thiophene, dppt2 = 2,3-bis(diphenylphosphino)thiophene) have been prepared and studied in terms of photoluminescence and electroluminescence properties. Both dimers exhibited two… read more here.
