Quantitative kinetic data were sought that would explain the mechanism of reactions catalyzed by BF3 compounds. A kinetic method and two model reactions--polymerization of isobutylene and decarbonylation of HC00H--were used to determine 1 the possibility of the catalysis proceeding through the stage of the formation of coordination compounds of BF3 with reagents aprotonic catalysis and 2 the nature of the catalytic activity and the amount of such activity of coordination compounds of BF3 with promoters. Aprotonic catalysis was not detected. In all reactions studied, catalysis of complex compounds of BF3 reduced to ordinary acidic catalysis. Compounds of BF3 with ether and with tetrahydrofuran were strong proton acids of a new type, dissociating by way of the C-H bond. The catalytic activity of the complex BF3 compounds was quantitatively determined.
