A highly efficient, two-step sequence method for the deoxygenation of hydroxyl groups has been developed. The method involves the preparation of the 2-(2-iodophenyl)ethyl methyl phosphite derivative of an alcohol using methyl dichlorophosphite and 2-(2-iodophenyl)ethanol. Treatment of the phosphite intermediate with (n-Bu)3SnH/AIBN in refluxing benzene cleanly produces the deoxygenation product...

We give a survey of new characterizations of finite solvable groups and the solvable radical of an arbitrary finite group which were obtained over the past decade. We also discuss generalizations of these results to some classes of infinite groups and their analogues for Lie algebras. Some open problems are discussed as well.

This is a survey of some aspects of Kurosh-Amitsur radical theory for groups which touches on history, some links and contrasts with ring radicals and some recent appearances of group radicals in the mathematical literature.

Disengagement from radical social groups is a complex process initiated by the experience of a crisis, or disillusionment causing a re-evaluation of involvement. This paper provides a review of the experiences that hinder group involvement and increases the likelihood of disengagement. Utilising the categorisation by Klandersman (2005) and Demant et al. (2008a), the factors are discussed under ...
