One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through
证明了以 1,3-二芳基丙烯醇或 1-芳基丙烯醇和甲醇作为 C1 源的一锅法合成 α-甲基酮。这种一锅异构化甲基化由市售的 Pd(OAc) 2催化,H 2 O 是唯一的副产物。机理研究和氘标记实验表明,在这些异构化-甲基化反应中,烯丙醇的异构化随后通过借氢途径进行甲基化。
