Phase selectively soluble dendritic derivative of 4-(n,n-dimethylamino)pyridine : an easily recyclable catalyst for Baylis-Hillman reactions
TLDR
In this article, the Baylis-Hillman reaction of various aryl aldehydes with methyl vinyl ketone and acrylonitrile in the thermomorphic binary system (DMF/cyclohexane, 1/1, v/v) has been investigated.Abstract:
The Baylis–Hillman reaction of various aryl aldehydes with methyl vinyl ketone and acrylonitrile in the thermomorphic binary system (DMF/cyclohexane, 1/1, v/v) has been investigated. The phase selectively soluble alkyl-modified dendritic DMAP catalyst could be easily recycled via phase separation which was induced by cooling the temperature from 60 °C to room temperature. The corresponding Baylis–Hillman adducts were obtained in good yields and the recycled and reactivated dendritic catalyst almost gave the same results.read more

Magnetic Nanoparticle‐Supported Morita–Baylis–Hillman Catalysts
TL;DR: A magnetic nanoparticle-supported quinuclidine was prepared and evaluated as a recoverable Morita-Baylis-Hillman catalyst as mentioned in this paper, which demonstrated comparable activity with that of DABCO and could be simply recycled with the assistance of an external magnet.
