  摘要：

  Z乙烯基碲化物是通过在非还原条件下使用n -BuLi–Te–H 2 O作为加氢灭菌系统对炔烃进行加氢灭菌而制得的。相同的系统促进了含有吸电子基团的烯烃的加氢酯化反应。锂和有机碲酸镁可对乙烯基卤化物，磷酸盐，磺酸盐和乙酸盐进行乙烯基取代，从而独家生成Z乙烯基碲化物。碲化物用容易获得的有机金属试剂进行金属转移，从而得到有价值的合成基础材料（例如，有机锂和有机铜酸盐）。乙烯基碲化物与Pd催化下的炔烃或与有机铜酸盐的反应，使偶联产物保持了双键的几何形状。

• Direct Michael addition to electron-deficient alkenes using diorganyl dichalcogenides (Te/S) and NaBH4/PEG-400

  Nucleophilic species of tellurium and sulfur were generated in situ from the reaction of the respective diorganyl dichalcogenides with NaBH4 in PEG-400 as solvent and selectively added to electron-deficient alkenes. Chalcogenolate anions were directly added at mild conditions by this simple procedure and in all cases furnished the respective Michael adducts in short reaction times and good yields.

  Olerins conjugated to electron-withdrawing groups (e.g. CHO, RCO, CO2R, CN) react rapidly with alkylselenols and tellurols generated in situ to give the corresponding beta-chalcogeno aldehydes, ketones, esters and nitriles. beta-Telluroketones are transformed into beta-telluroketals, which are beta-lithiocarbonyl synthons.

  vinylic halides, phosphates, sulphonates and acetates leading to the Z vinylic telluride exclusively. Tellurides are transmetallated with easily available organometallic reagents to give valuable synthetic building blocks (e.g. organolithiums and organocuprates). Reaction of vinylic tellurides with alkynes under Pd catalysis or with organocuprates gives the coupling products with retention of the double bond
