Summary
Reactions between triphenylmethyl hexachloroantimonate and 1,2-dimethoxy-4-(1-propenyl) benzene in methylene dichloride were studied by liquid chromatography, n.m.r. and visible spectroscopy. The system is characterised by slow initiation, shown to proceed through an addition reaction, and propagation only to the dimer stage, enabling simple analysis of the initiation kinetics. Similarities between this system and the anethole-trityl salt system were observed including initiation rate constants on the order of 10−3dm3 · mol−1 · sec−1 and the development of a chromophore at 545 nm which is probably due to a side reaction of the propagating cation.
