1,3-Dithienium- and 1,3-Dithiolenium Salts, II. Synthesis of Monocyclothioacetalized 1,3-Diketones from Silyl Enol Ethers

The 1,3-dithienium and 1,3-dithiolenium salts 3, available from the dithiols 1 or the cyclic thioacetals 4 (n=2, 3) by reaction with the acyl chlorides 2, trityl tetrafluoroborate (5), and sulfuryl chloride (7), react in good yields with the silyl enol ethers 10 to give the new monocyclothioacetalized 1,3-diketones 11.The synthetic potential of 11 as partially protected 1,3-diketones is demonstrated exemplarily by dethioacetalization to the 1,3-dicarbonyl compounds 13.

Synthesis of Stable Carbenium Salts from Cyclic Thioacetals - 1,3-Dithienium- and 1,3-Dithiolenium Salts

The reaction of the 2-substituted 1,3-dithianes 1 (n = 3) and the analogous 1,3-dithiolanes (n = 2) with sulfuryl chloride (2) with strict exclusion of moisture leads to the new 1,3-dithienium and 1,3-dithiolenium hydrogenedichlorides 3, respectively. - C
