-- J&K Scientific exclusively offers two monomers developed by Prof. Yin. The fossil resources derived 4,4’-biphenyldicarboxylic acid is a significant monomer in polymer industry [1]. However, its production route is lengthy and dirty with low selectivity, and the corresponding polymers are also poorly biodegradable. In view of increasing concerns about...

Prof. Xia started to work at Southern University of Science and Technology in 2018 as Chair Professor. And acting as Executive Dean of Grubbs Research Institute in Shenzhen in 2019. His research focuses on the synthesis, reactivity, and applications of organometallic conjugated system in the field of Materials Chemistry and...

What is Carbolong? Carbolong is a new class of multi-functional chain compounds containing multiple alkynyl groups. J&K is proud to exclusively supply Carbolong with following advantages: High activity and good selectivity Carbolong contains two excellent reactivity structure units propargyl alcohol and bialkynl. High efficiency Carbolong is able to achieve a variety...

Chiral imidazolidinone organocatalysts (developed by Professor David MacMillan in 2000) are small, bench-stable, and environmentally friendly organic molecules designed to be highly effective at enantiofacial discrimination (in lieu of big enzymes and metal catalysts) under a facile aerobic atmosphere. Excellent yields were reported by MacMillan et al. with a benzyl-substituted...

Coined by K. Barry Sharpless, Hartmuth C. Kolb, and M.G. Finn in 2001, click chemistry is a term used to describe reactions that rapidly and selectively react or “click” with each other in a predictable way to form physiologically stable products with heteroatom links (C-X-C). Widely used in the modification of biomolecules, surfaces,...

Metal-catalyzed cross-couplings are widely used for the C-C bonds formation in organic synthesis, particularly for unsaturated scaffolds production. However, there were several challenges to develop a general method for the direct deoxygenative cross-coupling of free alcohols, using as native sp3-hybridized functional groups. Challenges: the in situ cleavage of strong C–O...
