CARBON-13 NMR OF SOME S-METHYLTHIOLESTERS
Abstract:
H-1 and C-13 NMR chemical shifts for some alkyl-S-methyl-thiolesters (RCOSMe) are reported. The alfa-methylene and carbonyl carbons show lower field shifts when compared to analogous carboxylic acid derivatives. This behavior was explained by using charge densities and separation energies calculated by the AMl MO-SCF semiempirical method.
