C-H functionalisation of aldehydes using light generated, non-stabilised diazo compounds in flow

The difficulty in accessing and safely utilising non-stabilised diazo species has in the past limited the application of this class of compounds. Here we explore further the use of oxadiazolines, non-stabilised diazo precursors which are bench stable, in direct, non-catalytic, aldehyde C-H functionalisation reactions under UV photolysis in flow and free from additives. Commercially available aldehydes are coupled to afford unsymmetrical aryl-alkyl and alkyl-alkyl ketones while mild conditions and lack of transition metal catalysts allow for exceptional functional group tolerance. Examples are given on small scale and in a larger scale continuous production.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 22929-52-8, and how the biochemistry of the body works.Quality Control of Dihydrofuran-3(2H)-one

Lactone enols are stable in the gas phase but highly unstable in solution

2-Hydroxyoxol-2-ene (C5-1), the enol tautomer of gamma-butyrolactone, was generated in the gas phase as the first representative of the hitherto elusive class of lactone enols and shown by neutralization-reionization mass spectrometry to be remarkably stable as an isolated species. Ab initio calculations by QCISD(T)/6-311+G(3df,2p) provided the enthalpies of formation, proton affinities, and gas-phase basicities for gaseous lactone enols with four- (C4-1), five- (C5-1), and six-membered rings (C6-1). The acid-base properties of C4-C6 lactones and enols and reference carboxylic acid enols CH2=C(OH)2 (3) and CH2=C(OH)OCH3 (4) were also calculated in aqueous solution. The C4-C6 lactone enols show gas-phase proton affinities in the range of 933-944 kJ mol-1 and acidities in the range of 1401-1458 kJ mol-1. In aqueous solution, the lactone enols are 15-20 orders of magnitude more acidic than the corresponding lactones, with enol pKa values increasing from 5.6 (C4-1) to 14.5 (C6-1). Lactone enols are moderately weak bases in water with pKBH in the range of 3.9-8.1, whereas the lactones are extremely weak bases of pKBH in the range of -10.5 to -17.4. The acid-base properties of lactone enols point to their high reactivity in protic solvents and explain why no lactone enols have been detected thus far in solution studies.
