A convenient procedure to effect the Wittig and Horner–Wadsworth–Emmons reactions employing guanidine TBD and MTBD as base promoters was developed.Mild reaction conditions highly efficiently facilitated isolation of the final products(Figure1.5) [38].Further developments of theWittig reactionhave beenreported [39, 40]. A proposed mechanism of Heck reaction and other reactions using palladium compounds as catalysts and running via surface transient organometallic (STO) intermediates is presented in Figure 1.7. The formation of only one STO intermediate in all the Heck-, Suzuki-, Sonogashira-, and Stille-type coupling reactions during their reaction sequences was stressed. 万分感谢！ |

A convenient procedure to effect the Wittig and Horner–Wadsworth–Emmons reactions employing guanidine TBD and MTBD as base promoters was developed.Mild reaction conditions highly efficiently facilitated isolation of the final products(Figure1.5) [38].Further developments of theWittig reactionhave beenreported [39, 40]. A proposed mechanism of Heck reaction and other reactions using palladium compounds as catalysts and running via surface transient organometallic (STO) intermediates is presented in Figure 1.7. The formation of only one STO intermediate in all the Heck-, Suzuki-, Sonogashira-, and Stille-type coupling reactions during their reaction sequences was stressed. 有人提出了一种简便的，利用胍TBD和MTBD作为碱推动剂来促进Wittig和Horner–Wadsworth–Emmons 反应的方法。 温和的反应条件非常有利于终产物的分离（图1. 5）。还有人提出了对Witting 反应的更进一步的改进（方法）[39, 40]。 图1.7 介绍了一种 针对Heck反应和其它反应提出的机理，这些反应都采用钯化合物作为催化剂，中途有表面瞬间有机金属(STO)中间产物形成。特别强调指出的是在这些反应历程的所有Heck-, Suzuki-, Sonogashira-, 和 Stille-类 偶联反应中，只有一种STO中间产物形成。 |
