    Abstract The fluoride ion-catalyzed selective O-acylation of enol silyl ethers with acyl fluorides using KF and 18-Crown-6 is described herein. This catalytic system facilitated the practical and facile reaction of a variety of enol silyl ethers derived from aromatic/aliphatic ketones and aldehydes with acyl fluorides to afford useful and valuable enol esters.

    Abstract A copper-catalyzed construction of isothiochromenes and benzo[ b ]thiophenes via annulation with 1,1,1,3,3,3-hexamethyldisilathiane as a sulfur source is described. In the isothiochromene synthesis, the use of the disilathiane as a sulfur source successfully controls the regioselectivity of cyclization to afford the isothiochromene as the sole product. The present strategy can be applied to the synthesis of 2-aryl/2-alkylbenzo[ b ]thiophenes.
