Usage

General Description

4,4'-Ethylenedianisole is a chemical compound with the formula C14H14O2. It is an aromatic ether that is used primarily as a monomer in the production of poly(arylene ether) resins, which are high-performance thermoplastic materials known for their excellent mechanical, thermal, and chemical properties. 4,4'-Ethylenedianisole is also used as a building block in the synthesis of various specialty chemicals and polymers. 4,4'-Ethylenedianisole has a molecular weight of 214.26 g/mol and is a colorless to pale yellow liquid at room temperature. It is considered to have low acute toxicity, but its long-term effects on human health and the environment are not well documented. Therefore, proper handling and disposal procedures are recommended when working with this compound.

Boron carbonitride photocatalysts for direct decarboxylation: The construction of C(sp3)-N or C(sp3)-C(sp2) bonds with visible light

A metal-free protocol is established for the decarboxylative N-H or C(sp2)-H functionalization of acidsviametal-free boron carbon nitride (BCN) photocatalysis, delivering the desired products under ambient conditions. This methodology is applicable to the late-stage modification of pharmaceutical molecules and gram-scale experiments as well as in the recovery and reuse of the photocatalysts without the loss of reactivity. The developed photochemical reaction system fulfills the requirements of green and sustainable chemistry.

Enantioselective Radical SN2-Type Alkylation of Morita-Baylis-Hillman Adducts Using Dual Photoredox/Palladium Catalysis

An enantioselective radical alkylation of 4-alkyl-1,4-dihydropyridines with Morita-Baylis-Hillman (MBH) adducts has been reported. The SN2-type products are predominant. This reaction is enabled by dual photoredox/palladium catalysis. The alkylation products are provided in good yields with good regio- and enantioselectivity. The use of Ding's spiroketal-based bis(phosphine) (SKP) ligand is crucial to achieving satisfactory regio- and enantioselectivity. The resultant α,β-unsaturated ester can be easily reduced to a synthetically useful chiral allyl alcohol.
