Chloro-containing compounds are known to form carbocations, especially for chloride bonded to allylic or benzylic groups (ref.
The benzyl chloride is the most reactive, because the carbocation intermediate formed is stabilized by resonance into the aromatic group.
may indicate a greater usefulness for the carbocations
His most recent efforts have been directed towards solid-state NMR and x-ray crystallographic studies of isolable carbocations
, the thermal and photochemistry of iminium salts related to the visual pigments, and the use of photochemical methods for the fabrication of charge-mosaic piezodialysis membranes.
After setting out principles and practice, they cover the photogeneration of carbon-centered radicals, heteroatom-centered radicals, biradicals and radical pairs, radical ions, carbocations
and carbanions, and cargenes and nitrenes.
This result indicates that the reactivity of the carbocationic species generated during the polymerization process, which includes the initiating carbocations
and chain propagating carbocations
, were reactive enough to polymerize the vinylether groups of the VESFA, but not so reactive that they add to double bonds of the fatty acid portion of VESFA.
, Carbanions, Free Radicals, Carbenes, and Nitrenes.
12 Cyclobutyl, cyclobutyl-substituted and related carbocations
But the silicon cation proved more difficult to make than the carbocation
