Visible-Light-Induced Catalyst-Free Carboxylation of Acylsilanes with Carbon Dioxide

Intermolecular carbon-carbon bond formation between acylsilanes and carbon dioxide (CO2) was achieved by photoirradiation under catalyst-free conditions. In this reaction, siloxycarbenes generated by photoisomerization of the acylsilanes added to the C═O bond of CO2 to give α-ketocarboxylates, which underwent hydrolysis to afford α-ketocarboxylic derivatives in good yields. Control experiments suggest that the generated siloxycarbene is likely to be from the singlet state (S1) of the acylsilane and the addition to CO2 is not in a concerted manner.

Ruthenium-Catalyzed Brook Rearrangement Involved Domino Sequence Enabled by Acylsilane-Aldehyde Corporation

A ruthenium-catalyzed [1,2]-Brook rearrangement involved domino sequence is presented to prepare highly functionalized silyloxy indenes with atomic- and step-economy. This domino reaction is triggered by acylsilane-directed C-H activation, and the aldehyde controlled the subsequent enol cyclization/Brook Rearrangement other than β-H elimination. The protocol tolerates a broad substitution pattern, and the further synthetic elaboration of silyloxy indenes allows access to a diverse range of interesting indene and indanone derivatives.

Oxidative [1,2]-Brook Rearrangements Exploiting Single-Electron Transfer: Photoredox-Catalyzed Alkylations and Arylations

Oxidative [1,2]-Brook rearrangements via hypervalent silicon intermediates induced by photoredox-catalyzed single-electron transfer have been achieved, permitting the formation of reactive radical species that can engage in alkylations and arylations.

Synthesis of Acylsilanes via Catalytic Dedithioacetalization of 2-Silylated 1,3-Dithianes with 30% Hydrogen Peroxide

Acylsilanes were obtained efficiently from dedithioacetalization of 2-silylated 1,3-dithianes using 30% hydrogen peroxide catalyzed by iron(III) acetylacetonate-sodium iodide. The use of niobium(V) chloride as a catalyst instead of iron(III) acetylacetonate was also effective, except in synthesizing some acyltrimethylsilanes.

Environmentally benign deprotection of dithioacetals using 30% hydrogen peroxide catalyzed by Fe(acac)3 and sodium iodide

The reaction of dithioacetals with 30% hydrogen peroxide in the presence of catalytic amounts of iron(III) acetylacetonate and sodium iodide efficiently produced the corresponding carbonyl compounds in high yields.

Palladium-catalyzed carbonylative coupling reactions of aryl iodides with hexamethyldisilane (HMDS) to benzoyl silanes

A novel procedure for the palladium-catalyzed carbonylative synthesis of acyl silanes has been developed. Starting from aryl iodides and hexamethyldisilane (HMDS) various benzoyl silanes are produced in moderate to good yields.

A simple method for mild oxidation of α-hydroxysilanes to provide aroylsilanes

Potassium permanganate supported onto alumina in hexane-water is a good oxidizing agent to convert α-hydroxysilanes into acylsilanes. This mild oxidation afforded aroylsilanes having electron-donating groups attached to the aromatic ring, in 70-86% yield.

Synthesis of acylsilanes via oxidative hydrolysis of 2-silyl-1,3-dithianes mediated by N-bromosuccinimide

The oxidative method for the hydrolysis of 1,3-dithianes was applied to 2-silyl-1,3-dithianes using N-bromosuccinimide providing acylsilanes with good yields under a short reaction period. The oxidation of aroylsilanes to carboxylic acid was prevented by
