Abstract:
At present, alcohols are considered sustainable starting materials that can be used in organic synthesis for various organic transformations and the preparation of commodity chemicals. Acceptorless dehydrogenation (AD) and borrowing hydrogen (BH) are two important methods for activating alcohols for alkenylation and alkylation. These approaches are sustainable because their process liberates water and in some cases (i.e., AD) molecular hydrogen as clean byproducts. Moreover, this area of research has attracted significant attention in the catalysis community, and various transition metals have been used to explore the same. Herein, in this review, we focus on the development of Ru-based catalyst systems for C-alkylation/alkenylation reactions via the AD or BH approach. This review also features a comparative study of the various Ru-catalysts used to optimize the reaction conditions. Furthermore, we extensively cover the outcomes of the mechanistic studies to describe the reaction pathways.

02:24Reduction 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.
02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
02:47Alkynes 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.
02:15Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
