## Abstract The chemical shifts of the __N__โmethyl signals for a number of thioโoxamide and oxamide derivatives are unambiguously determined in the solvents chloroform, carbon tetrachloride, benzene, chlorobenzene, __o__โdichlorobenzene and nitrobenzene. The ASIS effect is discussed. The temperatu
## Abstract A PMR study of solvent effects on some __p__โsubstituted phenyltin chlorides (substituents = CH~3~, (CH~3~)~3~C, CH~3~O) is reported. Coโordination of solvent molecules to the tin atom leads to an unusual low field shift of the __o__โring protons. The results for __p__โtolytin trichlori
The "C NMR spectra of 21 catechin derivatives substituted at C-6/C-S by bromine and/or hydrogen and at oxygen by methyl, acetyl and/or hydrogen have been analysed in deuteriated acetone and chloroform. When a methoxy group is flanked by two bulky orrho substituents (6-Br and C4), the M e 0 and ortho
