New discoveries in chemical research and development in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Tukhtaev, Hamidulla B., once mentioned the application of 67604-48-2, Name is 5,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one, molecular formula is C15H12O5, molecular weight is 272.2528, MDL number is MFCD00006844, category is pyrrolines. Now introduce a scientific discovery about this category, Safety of 5,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one.
Acetylenes and nitriles as unconventional reactants for aza-Wittig reactions
The classic version of aza-Wittig reactions, namely, reactions between phosphazenes and compounds with polar double bonds, is widely employed in organic synthesis to produce C=N bonds. However, only a limited number of aza-Wittig reactions between phosphazenes and compounds with triple bonds is known, which has a lot to do with certain structural features of the reactants, wherein additional activation is required. This review provides a guide to those rare examples of aza-Wittig reactions with acetylenes and nitriles. A unique trait of these atom-economic processes is that they afford Wittig or new aza-Wittig reagents, respectively, which offers new opportunities for employing these reactions in organic syntheses, especially those of N-heterocyclic compounds.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 67604-48-2. Safety of 5,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one.
