Silver ketenide of empirical formula Ag2CCO is obtained by direct reaction of ketene or an in situ source of ketene such as acetic anhydride, isopropenyl acetate, vinyl acetate or phenyl acetate with certain silver salts, normally in the presence of

The intermolecular meta photocycloaddition of cycloalkenes to benzenes occurs with marked endo stereoselectivity, although the exo process would be favoured on purely steric grounds. Additions normally occur 2,6 to monoalkylbenzenes, but increasing t

The photoadditions of a variety of electron donor and electron acceptor ethenes to 1,4-benzoquinone have been studied. Spiro-oxetanes were formed in each case, though at markedly varying rates. The reactions were not stereoselective. In all cases exc

What then are the principal social effects of chemical pollution on people who live in large modern cities? We can divide these effects into several categories. Firstly there are effects on amenities, e.g. blackening of buildings by smoke, corrosion
