Díaz-Ortiz, Angel,De la Hoz, Antonio,Moreno, Andrés,Prieto, Pilar,León, Rafael,Herrero, María A.
, p. 2037 - 2038 (2002)
Microwave irradiation in solvent-free conditions induces cycloaddition reactions of pyrazine o-quinodimethane intermediates with electron-rich dienophiles within 10-15 min to afford quinoxaline derivatives in acceptable yields.
A general synthesis of diarylketones by means of a three-component cross-coupling of aryl and heteroaryl bromides, carbon monoxide, and boronic acids

Pd(OAc)2/di-1-adamantyl-n-butylphosphine (cataCXium A) is highly active in the three-component Suzuki carbonylation and represents the most general catalyst system reported up to now. A broad range of aryl/heteroaryl bromides and aryl boronic acids can be coupled to the corresponding diarylketones at low catalyst loadings.
