Liang, Wen-Yu published the artcilePd-catalyzed alkoxycarbonylation of alkenes promoted by H2O free of auxiliary acid additive, Name: Methyl octanoate, the main research area is ester green preparation; alkene alc carbon monoxide alkoxycarbonylation palladium catalyst water promoted.
The Pd-catalyzed and water promoted alkoxycarbonylation of alkenes using alcs. and carbon monoxide to afford esters RCHR1C(O)OR2 [R = n-Bu, cyclohexyl, Ph, etc.; R1 = H, Me; R2 = Me, Et, iPr] was reported. Water instead of Bronsted/Lewis acid was found to effectively improve the catalytic performance of Pd(MeCN)2Cl2-Xantphos system for alkoxycarbonylation of alkenes. Under the optimal conditions, the best yield of 97% was obtained for the target products Me 3-phenylpropanoate and Me 2-phenylpropanoate with L/B of 4.3 and TON of 192. The in situ high pressure FT-IR anal. verified that water played an important role in promoting formation and stability of Pd-H active species which was responsible for the efficient alkoxycarbonylation of alkenes. In addition, the ligand effect of Xantphos on this reaction was discussed.
Molecular Catalysis published new progress about Alcohols Role: RCT (Reactant), RACT (Reactant or Reagent). 111-11-5 belongs to class esters-buliding-blocks, name is Methyl octanoate, and the molecular formula is C9H18O2, Name: Methyl octanoate.
