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 eth

Described herein is an iodide-promoted insertion reaction of vinyltrimethylsilane into diaryl or dialkyl disulfides in the presence of iodine/KF leading to the production of a 1,1′-adduct, a dithioacetal derivative. This method also accomplishes in

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 succes

A novel methodology for in situ generation of Fischer-type metal-carbene complexes was developed. Photoirradiation to a mixture of an acylsilane and a cationic copper complex cleanly gave a Fischer-type copper-siloxycarbene complex, which was detecte

Carbamoylboranes were found to react with various aldehydes under heating conditions to give α-hydroxycarboxamides in good yields. A DFT study supports the mechanism, which involves thermally generated (amino)(boryloxy)carbene intermediates. To our

Acylsilanes have been known to undergo isomerization to siloxycarbenes under photoirradiation and the thus generated carbenes can be utilized for various synthetic reactions. But this carbene formation is not necessarily efficient with some alkanoyls
