Stiefel, published by Amer Chemical Society which was released on 11 December 1996. A new convenient, functional group-tolerant, transition metal-free route to aryl trifluoromethyl ketones under mild conditions is described. By virtue of its non-mathematical and strongly visual approach to bonding, it provides a most accessible text on the varied nature of the valence shell in d- block chemistry.
