Photolysis of Polyhalomethanes in the Presence of Nitrosoalkanes Formation of Acyl Alkyl Nitroxides (poly)halomethyl .-butyl nitroxides are normally only observed when the halogen atom is fluorine (see chapter 2) and not when it is chlorine, bromine or iodine. These nitroxides are often very unstable. Apparently, β-halogen elimination occurs easily (except for fluorine) to give halonitrones. Thes

Photochemically Initiated Reactions of Substituted 1,3-Dioxolanes and 1, 3-Oxathiolanes in CFCI3,cleavage of the new C-Cl bond gives the well stabilized cyclic carbonium ion and chloride anion. Nucleo-philic attack of chloride ion at the C-4 or C-5 carbon atom (involving inversion for a chiral C-4) leads to ring rupture and formation of the final product.

Jan Willem Hartgerinkll allows us critical distance. We can be ‘warn’d’ and ‘made asham’d’ by comedy’s depiction of vice, Congreve says elsewhere, because we can also reflect while we experience it.. It is this reflective capacity, this critical distance, that Congreve is attempting to assign to the novel by comparing i

The grounds of Richardson’s attack on the unlicensed theatres are hardly unusual: their location, easily accessible to the urban working class, encourages vice and idleness particularly in th

To further improve the R-D performance of the proposed highly scalable video compression scheme, we present in Sect. . an extension to the temporal breakpoint warping procedure (see Sect. .); the resulting HST-BPI can account fo
