• Promising biobased alternatives to polar aprotic solvents

  A report from Wageningen Food & Biobased Research commissioned by RIVM (the Dutch National Institute for Public Health and the Environment) has revealed a number of promising biobased alternatives to the controversial polar aprotic solvents NMP, DMAc and DMF. Wageningen Food & Biobased Research carr more

• Cool combination produces easier carbon bonds
  

  By combining two century-old techniques in organic chemistry, Syuzanna Harutyunyan is able to make organic compounds with greater ease and precision. Such compounds are important for drug discovery and development. Almost 90 percent of known active pharmaceutical ingredients contain one or more 'het more

• Pure industrial chemicals by gasifying lignocellulosic biomass

  VTT has demonstrated that lignocellulosic biomass can be successfully converted into pure BTX chemicals: benzene, toluene and xylene. The aim of this research is to enable the use of wood-based chemicals to replace crude oil in, for example, plastics, fuels, medicine and paints. Demand has grown rap more

• Calculating VOCs: Not all Low-VOCs Are Considered Equal

  Like most coatings, paints, and maintenance products, water repellents are expected to comply with increasingly stringent regulations of Volatile Organic Compounds (VOC), which are any volatile carbon compounds that engage in atmospheric photochemica more

The Chemicals Behind the ‘New Car Smell’

This graphic comes off the back of a number of requests for it to be added to the ‘Aroma Chemistry’ series. The characteristic ‘new car smell’, as with the majority of entries in this series, can’t be pinned down to just one compound – rather, it’s a complex mixture of chemicals that, combined, give more

What Causes the Smell of New & Old Books?

Everyone’s familiar with the smell of old books, the weirdly intoxicating scent that haunts libraries and second-hand book stores. Similarly, who doesn’t enjoy riffling through the pages of a newly purchased book and breathing in the crisp aroma of new paper and freshly printed ink? As with all arom more

Benzene Derivatives in Organic Chemistry

Benzene is a hugely important compound in organic chemistry. It consists of six carbon atoms joined together in a ring, with a hydrogen atom bonded to each carbon; by replacing one or more of these hydrogens with a functional group, a large number of different compounds can be formed. This graphic l more

• Silver(I)-catalyzed sequential hydroamination and Prins type cyclization for the synthesis of fused benzo--sultams

  An intramolecular annulation strategy has been developed for the synthesis of tetrahydrobenzo[e]pyrano[4,3-c][1,2]thiazine derivatives by means of coupling of aldehydes with 2-(4-hydroxybut-1-yn-1-yl)-N-arylsulfonamides using a catalytic amount of silver hexafluoroantimonate in toluene at 80 °C. Thi more

• Rare-earth metal bis(aminobenzyl) complexes supported by pyrrolyl-functionalized arylamide ligands: synthesis, characterization and styrene polymerization performance

  Acid-base reaction between the rare-earth tris(o-dimethylaminobenzyl) complexes Ln(CH2C6H4NMe2-o)3 and the pyrrolyl-functionalized arylamide ligands 2,5-Me2C4H2NCH2SiMe2NHC6H4R (R = H, (HL1); R = Cl-p, (HL2)) was investigated. Treatment of HL1 and HL2 with 1 equiv. of Ln(CH2C6H4NMe2-o)3 in toluene a more

• p-TsOH Promoted Synthesis of Benzo-Fused O-Heterocycles from Alkynols via Ring Contraction and C-O Scission Strategy

  We here report the first divergent synthesis of benzo-fused O-heterocycles by p-toluene sulfonic acid promoted cascade reactions involving alkyne hydration, double cyclization, ring contraction and C-O bond cleavage from alkynols. Reaction mechanism was validated by obtaining the x-ray structure of more
