Bis(1,5-cyclooctanediylboryl) sulfide (1) reacts with carboxylic esters to give the dithiocarboxylic 1,5-cyclooctanediylboryl esters 2a-f in high yields (2a: X-ray crystal structure analysis).Methanolysis of 2a-f leads to the dithiocarboxylic acids 5a-f, which form the corresponding piperidinium salts in the presence of piperidine.When cyclic esters (γ-, δ-lactones) are allowed to react with 1, the boryloxy-substituted dithiocarboxylic 1,5-cyclooctanediylboryl esters 3a-c are obtained.Key Words: (9-BBN)2S, reagent / OC-Sulfoborations / 1,2-Eliminations, of R2BOR', (R2B)2O / Dithiocarboxylic 1,5-cyclooctanediylboryl esters / Dithiocarboxylic acids
