Kinetically Controlled Acid–Base Interaction of Tetra-4-chloro-tetra-5(5-methyl-2-isopropylphenoxy)phthalocyanine with Nitrogen-Containing Organic Bases
摘要
Abstract
The interaction of the first synthesized tetra-4-chloro-tetra-5(5-methyl-2-isopropylphenoxy)phthalocyanine with pyridine, 2-methylpyridine, morpholine, piperidine, n-butylamine, tert-butylamine, diethylamine, and triethylamine in benzene was studied. The acid–base reaction is one of the rarely observed slow processes that forms kinetically stable proton transfer complexes. The structure of the complexes is described. The reactivity of tetra-4-chloro-tetra-5(5-methyl-2-isopropylphenoxy)phthalocyanine changes depending on the proton-acceptor ability and spatial structure of the nitrogen-containing base.
