Development of cationic gallium phthalocyanine catalysts for the chemistry of donor-acceptor cyclopropanes and its reactions with aldehydes

Cationic gallium phthalocyanine (RPcGa+) catalysts with SbF6- and Sb2F11 - /Sb3F16 - weakly coordinating anions were developed and used in the catalytic chemistry of donor-acceptor (D-A) cyclopropanes and related substrates. For the first time, these processes were implemented on the examples of [3 + 2]-cycloaddition/annulation reactions of D-A cyclopropanes and styrylmalonates with various aldehydes, as well as some other transformations with different substrates.
