In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C9H9BrO2, However, they have proven to be challenging because of the mutual inactivation of both catalysts. 214894-89-0, name is 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine. In an article£¬Which mentioned a new discovery about 214894-89-0
Nucleophilic addition of arylmethylzinc reagents (ArCH2ZnCl) to formaldehyde: An easy access to 2-(hetro)arylethyl alcohols
The selective addition of arylmethylmagnesium halides with formaldehyde giving arylethyl alcohols is extremely challenging. To circumvent the difficulties, in the current communication, we have reported on the nucleophilic addition of benzyl zinc reagents derived from inexpensive and abundant benzyl chlorides to paraformaldehyde. The reaction investigated herein is hitherto unknown and was found to be selective, operationally simple, atom- and step-economical and high yielding to deliver phenethyl alcohols utilized as key perfumery ingredients in 60?83% yields. After successful establishment of the reaction condition, the reaction was also scaled up successfully to deliver a large-scale preparation of the phenethyl alcohol.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 214894-89-0, help many people in the next few years.HPLC of Formula: C9H9BrO2
