DMP-mediated one-pot oxidative olefination of silyl ethers
Deng, Guisheng,Xu, Baihua,Liu, Chunyu
, p. 5818 - 5821 (2005)
Silyl ethers of arylic, allylic, propargylic and unactivated alcohols could be deprotected and oxidized with Dess-Martin periodinane, and the resulting aldehydes could be directly converted to the corresponding α,β- unsaturated esters in one pot with stabilized phosphoranes. Good selectivities were achieved upon a variety of protecting groups of alcohol by using this method. Other advantages of the protocol included simplicity of operations and high efficiency, as well as good to excellent yields.
Ruthenium-catalysed oxidative coupling of vinyl derivatives and application in tandem hydrogenation

The first ruthenium-catalyzed oxidative homo- and cross-coupling of exclusive vinyl derivatives giving highly valued 1,3-diene building blocks is reported. The catalytic system is based on readily available reagents and it mainly delivers the E,E isomer. This methodology also enables the synthesis of adipic acid ester derivatives in a one-pot fashion after in situ ruthenium-catalyzed hydrogenation.
Rhodium-catalyzed decarboxylative and dehydrogenative coupling of maleic acids with alkynes and alkenes
Itoh, Masaki,Shimizu, Masaki,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro
, p. 11427 - 11432 (2013/12/04)
The dehydrogenative coupling of maleic acids with alkynes proceeds smoothly accompanied by decarboxylation under rhodium catalysis to produce variously substituted α-pyrone derivatives. The catalyst system is also applicable to the coupling with 1,3-diyne
A comparison of Wittig and Wittig Horner (wadsworth emmons) reagents in reactions with some α-dicarbonyl compounds
Mawaziny, Sheila,Makky, Sadiah
, p. 61 - 69 (2007/10/03)
For the α-dicarbonyl compounds RCOCHO studied where R=H, Me or Ph it was found that the use of Wittig reagents resulted in higher overall yields of the expected products and that with neither type of reagent could the product OCHCH=CHCO2Et from glyoxal be isolated.
Ni-catalyzed homocoupling of 3-halopropenoates in the presence of water: Formation of hexenedioates
Kotora, Martin,Matsumura, Hiroshi,Takahashi, Tamotsu
, p. 236 - 237 (2007/10/03)
Homocoupling of (Z)-3-halopropenoates using a catalytic amount of NiCl2 and Zn in the presence of water in pyridine afforded a mixture of (Z)- and (E)-3-hexenedioates.
