Usage

General Description

9-Methylphenanthrene is a polycyclic aromatic hydrocarbon (PAH) compound consisting of three fused benzene rings with a methyl group attached to the ninth carbon atom. It is a colorless to light yellow solid with a strong odor, commonly found in fossil fuels, coal tar, and cigarette smoke. 9-Methylphenanthrene is classified as a potential human carcinogen, as it has been shown to induce tumors in animal studies. It is also considered to be toxic to aquatic life and has been found to persist in the environment for long periods of time. Due to its potential health and environmental hazards, exposure to 9-Methylphenanthrene should be avoided as much as possible.

Br?nsted Acid-Catalyzed Carbonyl-Olefin Metathesis: Synthesis of Phenanthrenes via Phosphomolybdic Acid as a Catalyst

Compared with the impressive achievements of catalytic carbonyl-olefin metathesis (CCOM) mediated by Lewis acid catalysts, exploration of the CCOM through Br?nsted acid-catalyzed approaches remains quite challenging. Herein, we disclose a synthetic protocol for the construction of a valuable polycycle scaffold through the CCOM with the inexpensive, nontoxic phosphomolybdic acid as a catalyst. The current annulations could realize carbonyl-olefin, carbonyl-alcohol, and acetal-alcohol in situ CCOM reactions and feature mild reaction conditions, simple manipulation, and scalability, making this strategy a promising alternative to the Lewis acid-catalyzed COM reaction.

Exhaustive Reduction of Esters Enabled by Nickel Catalysis

We report a one-step procedure to directly reduce unactivated aryl esters into their corresponding tolyl derivatives. This is achieved by an organosilane-mediated ester hydrosilylation reaction and subsequent Ni/NHC-catalyzed hydrogenolysis. The resulting conditions provide a direct and efficient alternative to multi-step procedures for this transformation that often require the use of hazardous metal hydrides. Applications in the synthesis of -CD3-containing products, derivatization of bioactive molecules, and chemoselective reduction in the presence of other C-O bonds are demonstrated.
