Silica Supported Acids (HClO4-SiO2, KHSO4-SiO2) as Eco-friendly Reusable Catalysts for Bromodecarboxylation of α,β-Unsaturated Carboxylic Acids using KBr under Solvothermal and Solvent-Free Conditions

Arisha, Samba Shiva Rao,Gugulothu, Yaku,Kamatala, Chinna Rajanna,Nagannagari, Maasi Reddy,Pulusu, Vijay Shekar,Utkoor, Umesh Kumar,Yelike, Hemanth Sriram

, p. 535 - 542 (2022/02/22)

A mild procedure has been developed for the bromodecarboxylation of α,β-carboxylic acids using nano silica supported SiO2-HClO4, SiO2-KHSO4 as catalysts and KBr as a bromine source in conventional solvothermal, ultrasonic assisted and solvent-free microwave assisted conditions. The α,β-unsaturated cinnamic acids were converted to corresponding β-bromo styrenes with high regioselectivity, while aliphatic α,β-unsaturated carboxylic acids afforded related β-bromo alkenes.

Rethinking Basic Concepts-Hydrogenation of Alkenes Catalyzed by Bench-Stable Alkyl Mn(I) Complexes

Weber, Stefan,St?ger, Berthold,Veiros, Luis F.,Kirchner, Karl

, p. 9715 - 9720 (2019/10/14)

An efficient additive-free manganese-catalyzed hydrogenation of alkenes to alkanes with molecular hydrogen is described. This reaction is atom economic, implementing an inexpensive, earth-abundant nonprecious metal catalyst. The most efficient precatalyst is the bench-stable alkyl bisphosphine Mn(I) complex fac-[Mn(dippe)(CO)3(CH2CH2CH3)]. The catalytic process is initiated by migratory insertion of a CO ligand into the Mn-alkyl bond to yield an acyl intermediate which undergoes rapid hydrogenolysis to form the active 16e Mn(I) hydride catalyst [Mn(dippe)(CO)2(H)]. A range of mono- A nd disubstituted alkenes were efficiently converted into alkanes in good to excellent yields. The hydrogenation of 1-alkenes and 1,1-disubstituted alkenes proceeds at 25 °C, while 1,2-disubstituted alkenes require a reaction temperature of 60 °C. In all cases, a catalyst loading of 2 mol % and a hydrogen pressure of 50 bar were applied. A mechanism based on DFT calculations is presented, which is supported by preliminary experimental studies.

An efficient conversion of alcohols to alkyl bromides using pyridinium based ionic liquids: A green alternative to appel reaction

Das, Pranab J.,Das, Jupitara,Das, Dimpee

, p. 651 - 654 (2018/02/09)

Pyridinium based ionic liquids namely 4-alkylpyridinium bromides were prepared and used for the conversion of alcohols to alkyl bromides in the presence of p-toluenesulphonic acid in the absence of volatile organic compounds. This solvent free procedure promises to be a much improved and environmentally benign alternative to the Appel reaction.

Facile continuous process for gas phase halogen exchange over supported alkyl phosphonium salts

Sharma, Priti,Sasson, Yoel

, p. 2824 - 2828 (2018/02/06)

Chloride-bromide halogen exchange was realized when a mixture of an alkyl chloride and an alkyl bromide were reacted over a supported molten alkyl phosphonium catalyst. Conversion was found to be near equilibrium in a tubular flow reactor at 150 °C and 1500 GHSV. The catalyst was prepared by impregnation of alumina or silica support and found to be highly stable for relatively long periods of time. A pathway for the catalytic cycle is proposed.

A mild method for the replacement of a hydroxyl group by halogen. 1. Scope and chemoselectivity

Munyemana, Fran?ois,George, Isabelle,Devos, Alain,Colens, Alain,Badarau, Eduard,Frisque-Hesbain, Anne-Marie,Loudet, Aurore,Differding, Edmond,Damien, Jean-Marie,Rémion, Jeanine,Van Uytbergen, Jacqueline,Ghosez, Léon

, p. 420 - 430 (2015/12/31)

α-Chloro-, bromo- and iodoenamines, which are readily prepared from the corresponding isobutyramides have been found to be excellent reagents for the transformation of a wide variety of alcohols or carboxylic acids into the corresponding halides. Yields are high and conditions are very mild thus allowing for the presence of sensitive functional groups. The reagents can be easily tuned allowing therefore the selective monohalogenation of polyhydroxylated molecules. The scope and chemoselectivity of the reactions have been studied and reaction mechanisms have been proposed.
