- Generation of cations from alkoxides: Allylation of propargyl alcohols
-
The reaction of alkoxides with boron trichloride results in the generation of cations in the absence of Bronsted acids. The absence of a Bronsted acid can make a difference in subsequent transformations such as allylation reactions. Copyright

- Unusual case of catalysis by palladium clusters
-
An unusual for Pd catalysts dehydration of α-alkyl and α, α′-dialkylbenzyl alcohols PhCR′R″OH (R′ = H, Me, Et, Bu; R″ = H, Me) occurs in the presence of the palladium(I) cluster [Pd4(CO)4(OAc)4] (1) in an inert atmosphere to form ethers PhCR′R″-O-CR′ R″ and water. The catalyst is an intermediate of cluster 1 reduction to Pd black, while neither the starting cluster 1, nor Pd black, which is the decomposition product, are active in the catalysis of this reaction.
