- A versatile palladium catalyst system for Suzuki-Miyaura coupling of alkenyl tosylates and mesylates
-
A general and effective palladium system for Suzuki-Miyaura coupling of alkenyl electrophiles under mild reaction conditions is reported. With the Pd(OAc)2/CM-phos system, a variety of alkenyl tosylates are coupled well with ArB(OH)2. Moreover, the first successful examples of using alkenyl mesylates in alkenylation are also described.

- Modern Friedel-Crafts chemistry. XVI. Sterically controlled cyclodehydration of selected arylalkanols
-
The cyclodehydration of three selected arylalkanols, namely 1,3-diphenyl-3-pentanol (I), 1,1,4-triphenyl-2methyl-1-butanol (II) and 1,1,4-triphenyl-2-methyl-2-butanol (III) with Friedel-Crafts catalysts was investigated.A reasonable interpretation of the reaction products was suggested, steric hindrance was found to have major influence on the course of the reaction.
