The Vilsmeier reagent derived from N-formylmorpholine produces chlorothioformates from primary and secondary alkyl xanthates. The major side products are the corresponding alkyl chlorides. Secondary alkyl chlorothioformates give lower yields due to their instability. Treating xanthates with other common chlorinating agents (oxalyl chloride, thionyl chloride) gives only dialkyl thiodicarbonates. Georg Thieme Verlag Stuttgart.

Irradiation of norbornene and silver or thallium trifluoromethanesulfonate in acetonitrile solutions results in the efficient formation of exo-2-(cyanomethyl)bicycloheptane.Investigation of the scope of this reaction established that (a) copper(I or II) salts are not effective, (b) propionitrile and methanol give analogous norbornene-solvent adducts, and (c) acetonitrile addition is observed for several cyclic and acyclic olefins.Investigation of the mechanism of solvent addition indicates that the reaction is initiated by photoinduced electron transfer to silver(I) from coordinated norbornene.Reaction of the resulting norbonene cation radical with acetonitrile yields norbornyl cation and cyanomethyl radical.Free-radical chain addition of the cyanomethyl radical to norbornene then leads to product formation.In ethereal solvents, metal ion catalyzed photodimerization of norbornene has previously been reported for copper(I) salts.This reaction can also be effected by copper(II) and silver(I) salts, but not by Tl(I) salts.

In the cases of 2-methylbutane and 2-methylpentane the formation of tertiary sulphochlorides in the sulphochlorination of the parent hydrocarbons could be established by means of 13C-n.m.r.-spectroscopy.The relative rates of the various C-H-bonds in 2-methylbutane, 2-methylpentane and 3-methylpentane in the sulphochlorination reaction were determined.The relative rates of the tertiary C-H-bonds in the sulphochlorination were considerably lower than the corresponding values for the chlorination of the branched-chain paraffins.
