The 10-, 11-, 19- and 20-mono-13C-all-trans-retinals were synthesized with >98% chemical purity and 92% 13C incorporation from 13C-labelled acetonitrile and 13C-labelled methyl iodide. Their 13C-13C and 13C-1H NMR coupling constants were measured.

Solid-state /sup 13/C magic-angle sample spinning (MASS) NMR has been used to study lyophilized dark-adapted purple membrane containing /sup 13/C-labeled retinals. C-10, C-11, and C-12-labeled derivatives each showed two lines, assigned to the coexis

BF2 complexes of alkylated pyrromethenes were prepared by reacting the corresponding pyrromethenes with BF3·OEt2 under basic conditions. A striking aspect of these complexes is a pronounced fluorescence in organic solvents, even at room temperature,
