A new facile and rapid polycondensation reaction of 4,4Π-(hexafluoroisopropylidene)-N,NΠ-bis(phthaloyl-L-leucine) diacid chloride (1) with several aromatic diamines, including benzidine (2a), 4,4Π-diaminodiphenyl methane (2b), 1,5-diaminoanthraquinone (2c), 4,4Π-sulfonyldianiline (2d), 3,3Π-diaminob
## Abstract An efficient synthesis of 5βheteroarylβ and 5,7βbis(heteroaryl)azulene derivatives was established for first time. The reaction proceeded through electrophilic substitution of 1,3βdiβ__tert__βbutylazulene (**1**) with the triflates of Nβcontaining heterocycles, in the presence of excess
