  Te-1-Acylmethyl and Te-1-Iminoalkyl Telluroesters: Synthesis and Thermolysis Leading to 1,3-Diketones and O-Alkenyl and O-Imino Esters

  摘要：

  A series of Te-1-acylmethyl carbotelluroates was prepared in good isolated yields from the reaction of potassium carbotelluroates with -haloketones in acetonitrile. Thermolysis of the telluroesters afforded vinyl esters in 20-50% yields, while treatment of the carbotellurorates with potassium t-butanolate led to 1,3-diketones in 30-75% yields with the liberation of black tellurium. The reaction of potassium carbotelluroates with -haloaceto oximes gave O-acyl oximes in 50-70% yields via Te-1-iminomethylcarbotelluroates.

  In the current study Ru(II) vinylidene complexes of the general type: Cl 2 Ru=C=C(H)R}(PR' 3 )L (R = Ph, SiMe 3 , R'=Ph, Cyclohexyl (Cy) and L = phosphine or N-heterocyclic carbene) are synthesized and tested for the addition of carboxylic acids to terminal alkynes. A careful choice of the catalytic system, substrate and carboxylic acid gives access to alk-1-en-2-yl esters, alk-1-en-1-yl esters or

  在目前的研究中，一般类型的 Ru(II) 亚乙烯基配合物：Cl 2 Ru=C=C(H)R}(PR' 3 )L (R = Ph, SiMe 3 , R'=Ph, Cyclohexyl (Cy ) 和 L = 膦或 N-杂环卡宾) 被合成并测试羧酸与末端炔烃的加成。仔细选择催化体系、底物和羧酸可以获得 alk-1-en-2-yl 酯、alk-1-en-1-yl 酯或 enyne 二聚产物。此外，通过用 AgBF 4 处理其中一种配合物，对合成类似的 14 电子物种进行了扩展，并研究了其对催化活性和选择性的影响。
