Optical activity owing to restricted rotation (atropisomerism) has been demonstrated in two phenylthiophenes 2-(6-methyl-2-nitro-phenyI)-3-thiophenecarboxylic acid (41), which rapidly racemized in solution, and 2,5-dimethyl-4- (6 -methyl-2 -nitrophenyl) 3-thio-phenecarboxylic acid (42), which was optically stable (at room temperature). Recently the first bithienyl, 2,2 -dicarboxy-4,4 -dibromo-5,5 -dimethyl-3,3 -bithienyl (43), has been resolved into optical anti-podes which were optically stable.

Alkyl- and aryl-l,3,4-oxadiazoles are neutral compounds and 2-amino derivatives are weak bases. Protonation is believed to occur at ring nitrogen in position 3 which facilitates ring cleavage in aqueous acid. The pKa (water) value of 2-amino-5-methyl-l,3,4-oxadiazole is 2.37 and values in the range 2.3-2.7 have been recorded for 2-amino-5-phenyl- and 2-7V-methyIamino-5-phenyI-l,3,4-oxadiazoIe in 50% aqueous ethanol. In the same solvent pK values of the more basic imines, 4-methyl-2-phenyl- and 4,AT-dimethyl-2-phenyl-A2-...
