9.10.1.4.4.4.1 Variation 1: Manganese-Assisted Coupling Reactions

DOI: 10.1055/sos-SD-009-00363

Schatz, J.Science of Synthesis, (20019387.

Rieke manganese shows a superior reactivity towards oxidative addition to organic halides, even in cases when Rieke zinc or magnesium fail to undergo a similar reaction.[‌903‌] The reactive thienylmanganese intermediates so obtained undergo palladium-catalyzed cross coupling with aryl iodides or aroyl chlorides to give 291 and 292, often in good yields (Scheme 126).[‌901‌,‌903‌,‌1084‌,‌1085‌]
