23. The branched aldehyde seems to predominate also in the case of 4-vinylpyridine, but the aldehydes are produced in such a small quantity that no accurate determination of the isomeric ratio was possible. 4-Ethylpyridine and 2-ethylpyridine have been determined by comparison with authentic samples commercially available.

31. The charge densities on the other atoms of the pyridyl ring as well as of the vinyl group are very similar in all the substrates. The nitrogen atom shows a negative charge as well as the carbon atom present in the position two of the double bond whereas a small positive charge is present on the vinyl carbon atom bound to the heteroaromatic ring.
