The effect of the structure and the medium on the position and intensity of the absorption bands in the UV spectra that attest to the presence of a single conjugation system in N-vinylpyrroles is thoroughly analyzed. The tendency for a reduction in t

1. The homolytic addition of dialkyl phosphites to the divinyl ethers of gem-diols leads to the formation of 5-methyl-4-phosphonomethyl-1,3-dioxolanes. 2. The cyclization goes stereospecifically with the formation of the cis-5-methyl-4-(dialkylphosph

The position of the substituants in 2, 3-dialkyl-1-vinylpyrroles and 7-methyl-1 vinyl-4,5,6,7-tetrahydroindole was established on the basis of the 1H and 13C NMR spectra. It was found that the S-trans conformation of the N-vinyl group is preferred. I

The NQR-35Cl spectra of a series ofβ,β-dichlorovinylketones exhibit a linear dependence of the NQR-35Cl frequencies on theσ-parameters of the substituents. The behavior of the NQR frequencies of the halogens is significantly influenced by the conf

1. A number of 1,3-dioxolanes almost instantly convert the magnesium bromide present in ether solutions of ethylmagnesium bromide into insoluble associates, which then bind the diethylmagnesium remaining in solution at a relatively slow rate to give

1. Fifteenβ-hydroxyethyl ethers, fiveβ-hydroxyethyl sulfides, and eightα-hydroxyethylamines were analyzed in a comparison of the IR spectrum. 2. An appreciable simplification of the spectrum (disappearance of the bands at 1010 and 1040 cm−1) was

1. The bis-(1,3,3-trichloroallyl) ether of ethylene glycol was isolated as the result of the homolytic addition of carbon tetrachloride to the divinyl ethers of diols. 2. The homolytic reaction of aldehydes with the divinyl ethers of diols leads to a
