  摘要：

  铜络合物首先被用作催化剂，通过使用过氧化二叔丁基（DTBP）的交叉脱氢偶联（CDC）反应，将环醚和羧酸的非反应性C（sp 3 ）-H键氧化酯化。各种各样的羧酸都可以与环醚反应，具有良好或优异的收率，这表明铜盐是CDC反应的一种有希望的新型催化剂。在克级测试下，仅以0.01％的催化剂负载量，周转数（TON）即可达到8400，收率达到84％，这证明了其实际用途。

  crème de la crème! A practical and simple Bu4NI‐catalyzed CO bond formation was achieved by using a cross‐dehydrogenative coupling (CDC) reaction with tert‐butyl hydroperoxide (TBHP) as the ultimate oxidant (see scheme; R1=aryl, heteroaryl, alkyl; R2, R3=alkyl, alkyl halide). This approach is the most straightforward method to date for the synthesis of α‐acyloxy ethers. A plausible mechanism has been proposed

  We demonstrated a dehydrogenative cross coupling between a benzyl alcohol and C(sp³)–H bond for the construction of a C–O bond. This method reveals a new strategy for the direct use of benzyl alcohols in the synthesis of esters with the use of copper as a catalyst and TBHP as an oxidant.

  six-coordinate structure. An efficient copper porphyrin-catalyzed cross-dehydrogenative coupling (CDC) esterification reaction between C(sp3)–H and carboxylic acids using di-tert-butyl peroxide (DTBP) as an oxidant was established. The kinetic isotope effect (KIE) indicated that C(sp3)–H bond cleavage was the rate-determining step of this CDC reaction.

  An unexpected Cu-catalyzed oxidative cleavage of the C(sp(3))-C(sp(3)) bond in glycol ethers by using air or molecular oxygen as the terminal stoichiometric oxidant is demonstrated. As a result, the corresponding alpha-acyloxy ethers and formates of 1,2-ethanediol are formed by direct coupling of carboxylic acids and aldehydes with glycol ethers under the reaction conditions. This method represents the first example of Cu-catalyzed aerobic cleavage of saturated C-C bond in ethers.
