Mild and efficient tetrahydropyranylation of alcohols-catalysis by lithium perchlorate in diethyl ether
Babu, Boga Sobhana,Balasubramanian, Kalpattu Kuppuswamy
, p. 9287 - 9288 (1998)
Treatment of 3,4-dihydro-2H-pyran 1 with various alcohols 2 - 10 furnished the tetrahydropyranyl ethers 11 - 19 in the presence of 5M lithium perchlorate in diethyl ether (5M LPDE), which is essentially a neutral medium.
Selective Semi-Hydrogenation of Terminal Alkynes Promoted by Bimetallic Cu-Pd Nanoparticles
Buxaderas, Eduardo,Volpe, María Alicia,Radivoy, Gabriel
, p. 1466 - 1472 (2019/03/07)
The selective semi-hydrogenation of terminal alkynes was efficiently performed, under mild reaction conditions (H 2 balloon, 110 °C), promoted by a bimetallic nanocatalyst composed of copper and palladium nanoparticles (5:1 weight ratio) supported on mesostructured silica (MCM-48). The Cu-PdNPS@MCM-48 catalyst, which demonstrated to be highly chemoselective towards the alkyne functionality, is readily prepared from commercial materials and can be recovered and reused after thermal treatment followed by reduction under H 2 atmosphere.
Room-Temperature Gold-Catalysed Arylation of Heteroarenes: Complementarity to Palladium Catalysis
Cresswell, Alexander J.,Lloyd-Jones, Guy C.
supporting information, p. 12641 - 12645 (2016/08/30)
Tailoring of the pre-catalyst, the oxidant and the arylsilane enables the first room-temperature, gold-catalysed, innate C?H arylation of heteroarenes. Regioselectivity is consistently high and, in some cases, distinct from that reported with palladium ca
