A simple method for the cleavage of methoxymethyl (MOM)-ether and ester derivatives using bismuth trichloride (BiCl3) is described. The alkyl, alkenyl, alkynyl, benzyl and anthracene MOM ether derivatives, as well as MOM esters of both aliphatic and aromatic carboxylic acids, were deprotected in good yields. To better understand the molecular roles of BiCl3and water for MOM cleavage, two possible binding pathways were investigated using the density functional theory (DFT) method. The theoretical results indicate the differential initial binding site preferences of phenolic and alcoholic MOM substrates to the Bi atom and suggest that water plays a key role in facilitating the cleavage of the MOM group.

The anodic decarboxylation of 3-oxanonanoic acid (2a) and 3-oxapentadecanoic acid (2b) in methanol leads exclusively to products of the non-Kolbe electrolysis.The influence of coelectrolysis, solvent, current density, degree of neutralization and chain length of the alkoxy group on the anodic decarboxylation of 2a, b have been investigated.An extended alkyl chain in the alkoxy group, coelectrolysis with long-chain fatty acids, ethanol or dimethylformamide as solvent, and a high current density favor the Kolbe coupling against the non-Kolbe electrolysis.Key Words: Kolbe electrolysis/ Non-Kolbe electrolysis/ Carboxylic acids, α-alkoxy-/ Solvent effects

Acyclic acetals and 1,1-di(alkylthio)alkanes enter into exchange reactions in the presence of aprotic acids and of the KU-2 cation-exchange resin with the formation of the unsymmetric acetals and 1-alkoxy-1-alkylthioalkanes.In reaction with ethylal di(ethylthio)methane forms 3,5,7-trioxanonane in addition to ethylthioethoxymethane. 2-Methyl-4-thia-2-hexene was found in the products from the reaction of 1,1-di(ethylthio)-2-methylpropane with methylal.
