Abstract

Abstract Tris (phosphanylamide) early/late heterobimetallic Zr/Co complexes, ClZr (R′ NPR 2) 3 CoI [R′= iPr, R= Ph (1), R′= 2, 4, 6-trimethylphenyl, R= iPr (2), R′= R= iPr (3)], have been utilized as catalysts for the cross-coupling of alkyl halides with n-octylmagnesium bromide. While yields are consistently higher for alkyl bromide substrates, it is found that these unusual heterobimetallic complexes are also active towards more challenging alkyl ...
