Grignard reagents have been generated from reluctant aryl chlorides and bromides using controlled microwave heating to establish a safe, productive and reproducible method. In the synthesis of a novel HIV-1 protease inhibitor, microwave irradiation was both used to generate the starting arylmagnesium halide and to promote a subsequent Kumada coupling.

A palladium(0) nanocluster supported on hydrotalcite has been prepared and tested for the Suzuki coupling reaction. The prepared catalyst showed very efficient catalytic activity for cross coupling of iodo- and bromoarenes under very mild reaction conditions, affording >90% yield. Under the optimized reaction conditions, chloroarenenes also showed very good reactivity. Transmission electron microscopic imaging data showed the formation of very small Pd(0)-nanoclusters (d = 2.2 ± 0.5 nm) well dispersed on the support, which enhanced the activity and stability of the catalyst for the Suzuki cross-coupling reaction. This catalytic system offers an easy method of preparation with good activity and reusability up to five cycles.

Aryl carbamates were for the first time applied as electrophiles in the cross-coupling with arylsilanes via nickel or iron catalysis to construct valuable biaryl compounds. This new coupling reaction features a good group tolerance and non-sensitivity to steric hindrance on both aryl carbamates and arylsilanes. (Figure presented.).
