Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Guo, WD; Liu, L; Yang, SQ; Chen, XC; Lu, Y; Giang, VT; Liu, Y. The CAS is 103-26-4. Through research, I have a further understanding and discovery of Methyl 3-phenyl-2-propenoate
Tandem bis-alkoxycarbonylation of alkynes allows for the preparation of 2-substituted succinates from alkynes and nucleophile alcohol via two successive alkoxycarbonylation with advantages of 100 % atomic economy and simplified one-pot operation. Herein, the one-pot tandem bis-alkoxycarbonylation of alkynes was accomplished over the bi-functional catalytic system containing Xantphos-modified Pd-complex and Lewis super-acid of Al(OTf)(3). It was found that, via the synergetic catalysis, the involved Xantphos-modified Pd-complex was responsible for the activation of CO and the alkynes through coordination to Pd-center while Al(OTf)(3) was in charge of the activation of the alcohol to facilitate the formation of [Pd-H](+) active species. The in situ high-pressure FT-IR analysis, coupled with H-1/C-13 NMR spectral characterizations, confirmed that the introduced Al(OTf)(3) with intensive oxophilicity (via acid-base pair interaction) was able to activate nucleophilic MeOH to be a reliable proton-donor (i. e. hydride-source) to warrant the formation and stability of [Pd-H](+) species upon the oxidation of Pd-0 by H+ (Pd-0+H+->[Pd-II-H](+)). Over the developed bi-functional catalytic system, the yields of the target diesters were obtained in the range of 36 similar to 86 % in this sequence with the wide substrate scope.
