g-Methoxycarbonylbenzoyl chloride reacts with Lewis acids in S02/CD2C12 to give solutions of carbenium salts which can be identified using 13 C nmr spectroscopy. Acyl dialkyloxonium salts' and one example each of a diacyl alkyloxonium-2 and a triacyloxonium-3 salt have been reported but nmr data, e
## Abstract The conformations of dihydrolysergamides and 10โmethoxydihydrolysergamides have been inferred from the study of the chemical shifts of the amide hydrogens and their temperature dependence. The ^13^C chemical shifts have been shown to be sensitive to conformational changes of the piperid
