, p. 4195 - 4198 (2006)
(Chemical Equation Presented) New and improved bis(thio)urea catalysts were synthesized from isophoronediamine (IPDA) and tested in the Morita-Baylis-Hillman reaction. The best results were achieved in the reaction of 2-cyclohexen-1-one with cyclohexaneca

, p. 1943 - 1946 (2005)
A new double-activation catalysis is presented for the Morita-Baylis- Hillman (MBH) reaction of an α,β-unsaturated ketone and an aldehyde by the combined use of a heterobimetallic asymmetric complex and tributylphosphine ((n-Bu)3P) to afford th
Merging metal-organic framework catalysis with organocatalysis: A thiourea functionalized heterogeneous catalyst at the nanoscale
Luan, Yi,Zheng, Nannan,Qi, Yue,Tang, Jia,Wang, Ge
, p. 925 - 929 (2014)
A new thiourea-containing metal-organic framework (MOF) catalyst was synthesized. It overcomes recycling, self-aggregation and solvation issues that exist in homogeneous thiourea catalysts. Nanomorphology was introduced to increase the dispersion of the solid catalyst in solvent. Acetalization and Morita-Baylis-Hillman reactions were catalyzed using the new thiourea MOF catalyst. This journal is the Partner Organisations 2014.

In aqueous media, imidazole was found to catalyse Baylis-Hillman reactions of cyclopent-2-enone with various aldehydes to afford the desired adducts with high yields.
Efficient Baylis-Hillman reactions promoted by mild cooperative catalysts and their application to catalytic asymmetric synthesis
Yamada, Yoichi M. A.,Ikegami, Shiro
, p. 2165 - 2169 (2000)
Baylis-Hillman reactions were promoted by mild cooperative catalysts of tributylphosphine with phenols such as (±)-1,1'-bi-2-naphthol (BINOL) in THF to give α-methylene-β-hydroxyalkanones in high yield. The reactions proceeded much faster in the presence

We demonstrate herein a facile strategy to engineer versatile catalytically active coordination interspace in the same primitive metal-organic framework (MOF) for variable heterogeneous catalysis. Different functional ligands can be reversibly inserted into and removed from proto-LIFM-28 individually or successively to bring in single or binary catalytic sites for specific reactions and switch the parent MOF to multipurpose catalysts. Alcohol-oxidation, Knoevenagel-condensation, click, acetal, and Baylis-Hillman reactions are achievable through simple exchange of a single catalytic spacer, while sequential or stepwise reactions are designable via selective combination of two catalytic spacers with different functionalities, thus making proto-LIFM-28 a multivariate MOF for multiuse and economic catalysis.
