Access to Trisubstituted Fluoroalkenes by Ruthenium-Catalyzed Cross-Metathesis

Although the olefin metathesis reaction is a well-known and powerful strategy to get alkenes, this reaction remained highly challenging with fluororalkenes, especially the Cross-Metathesis (CM) process. Our thought was to find an easy accessible, convenient, reactive and post-functionalizable source of fluoroalkene, that we found as the methyl 2-fluoroacrylate. We reported herein the efficient ruthenium-catalyzed CM reaction of various terminal and internal alkenes with methyl 2-fluoroacrylate giving access, for the first time, to trisubstituted fluoroalkenes stereoselectively. Unprecedent TON for CM involving fluoroalkene, up to 175, have been obtained and the reaction proved to be tolerant and effective with a large range of olefin partners giving fair to high yields in metathesis products. (Figure presented.).

Hydroformylation of natural olefins with the [Rh(COD)(μ-OMe)]2/TPPTS complex in BMI-BF4/toluene biphasic medium: Observations on the interfacial role of CTAB in reactive systems

The complex [Rh(COD)(μ-OMe)]2 in presence of TPPTS (TPPTS = triphenylphosphinetrisulfonate) was evaluated as catalyst precursor for the in situ hydroformylation of natural olefins (eugenol, estragole and safrole) in biphasic media BMIm-BF4/toluene. Under moderate reaction conditions, the substrates showed the following reactivity order: eugenol > estragole > safrole. The rhodium system showed a high activity and selectivity towards the desired aldehydes. It was found that the use of cetyltrimethylammoniun bromide (CTAB) as phase transfer agent inhibits the hydroformylation reaction. The catalytic phase can be recycled up to four times without evident loss of activity or selectivity. In this work we report the use of an ionic liquid with hydrophilic character, without using water in the reaction medium.

Carbonylative Transformation of Allylarenes with CO Surrogates: Tunable Synthesis of 4-Arylbutanoic Acids, 2-Arylbutanoic Acids, and 4-Arylbutanals

In this Communication, procedures for the selective synthesis of 4-arylbutanoic acids, 2-arylbutanoic acids, and 4-arylbutanals from the same allylbenzenes have been developed. With formic acid or TFBen as the CO surrogate, reactions proceed selectively and effectively under carbon monoxide gas-free conditions.
