Abstract:
A rhodium-catalyzed reductive carbonylative cyclization for the direct synthesis of 3-silyl-1-indanones from readily available aryl alkynes and hydrosilanes is described. This transformation concurrently introduces a silicon moiety and constructs the indanone core under an atmosphere of carbon monoxide, exhibiting high regioselectivity. The reaction features a broad substrate scope across a range of symmetrical and unsymmetrical alkynes as well as diverse hydrosilanes. Preliminary mechanistic studies support a pathway involving hydrosilylation, rate-limiting C-H activation, and carbonylation. This work provides a concise and practical route to valuable organosilicon scaffolds.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.

Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.
