A general and efficient method for the palladium-catalysed conversion of allylic alcohols into their corresponding dienes
Ostrowski, Karoline A.,Vogelsang, Dennis,Vorholt, Andreas J.
, p. 1302 - 1305 (2016)
A general method was established, converting a broad range of allylic alcohols directly and quantitatively into their corresponding dienes. The developed protocol allows the direct use of allylic alcohols, circumventing the need for their derivatisation into more reactive precursors, thereby minimising waste production with water as the sole co-product.

The synthesis of telechelic polymers which contains two OH groups using 8-boraindane/oxygen controlled radical initiator was analyzed. It was observed that process is centered on bicycloborane compound which serve as functional initiator. In the polymeriz

The telomerization of butadiene with methanol was investigated in the presence of different palladium catalysts modified either with triphenylphosphine (TPP) or 1,3-dimesityl-imidazol-2-ylidene (IMes) ligand. When pure butadiene was used as substrate, a m

Telomerization of 1,3-Butadiene with Carbon Dioxide: A Highly Efficient Process for δ-Lactone Generation
Balbino, Jo?o M.,Dupont, Jairton,Bayón, J. Carles
, p. 206 - 210 (2018)
A very efficient and selective telomerization of 1,3-butadiene with CO2 that leads to the δ-lactone (3-ethylidene-6-vinyltetrahydro-2H-pyran-2-one) was obtained using palladium acetate and tris(p-methoxyphenyl)phosphine as a catalyst in the presence of p-hydroquinone, N,N-diisopropylethylamine, and acetonitrile. A high turnover number of 4500 with 96 % selectivity to the δ-lactone was obtained after 5 h reaction at 70 °C. The reaction was deactivated by the presence of different 1,3-dialkylimidazolium ionic liquids, possibly by the formation of stable and inactive palladium-imidazole-2-ylidene carbenes.
The multiple roles of imidazolium ionic liquids in transition-metal catalysis: The palladium-catalyzed telomerization of 1,3-butadiene with acetic acid

, p. 972 - 977 (2015)
The telomerization of 1,3-butadiene with acetic acid catalyzed by palladium(II) acetate associated with a series of phosphines in 3-(2-methoxyethyl)-1-methylimidazolium acetate was used to investigate the role of the ionic liquid. The ionic liquid plays multiple roles in this reaction as it acts as the solvent, stabilizer, ligand, and cocatalyst. The reaction performed in the presence of Dan2phos, a trifluoromethylated sulfonated triarylphosphine, at 100 °C for 24 h gave a turnover number of 14 600 with 89 % selectivity to telomers at 75 % 1,3-butadiene conversion and complete acetic acid conversion.
Telomerization of 1,3-butadiene with highly substituted alcohols using Pd/NHC-catalysts — Structure-reactivity-relationship of the O-nucleophile

, p. 526 - 532 (2016/08/24)
Catalytic telomerization of 1,3-butadiene with alcohols is a catalytic reaction and an effective tool to synthesize 2,7-octadienyl ethers with different characteristics depending on the alcoholic substrate. While Pd/phosphine type catalysts were studied i
