Abstract:
The syntheses of the 2,9‐dimesityl‐1,10‐phenanthroline ( dmesp ) metal complexes, [Cu(dmesp)(MeCN)]PF 6 ( 1 ), [Cu(dmesp) 2 ]PF 6 ( 2 ), Fe(dmesp)Cl 2 ( 3 ), Co(dmesp)Cl 2 ( 4 ), Ni(dmesp)Cl 2 ( 5 ), Zn(dmesp)Cl 2 ( 6 ), Pd(dmesp)MeCl ( 7 ), Cu(dmesp)Cl ( 8 ), and Pd(dmesp) 2 Cl 2 ( 9 ), in good to high yields are described. These complexes were characterized by 1 H and 13 C NMR spectroscopy, HR–MS (ESI and/or APPI), and elemental analysis (CHN). The solid‐state structures of complexes 1 – 8 were determined by single‐crystal X‐ray analysis and their photophysical properties were also characterized. To demonstrate the versatility of this new platform, complexes 3 – 5 , 8 , and 9 were employed in the catalytic oligomerization of ethylene using modified methyl aluminoxane (MMAO) as the cocatalyst, where Co(II) and Ni(II) complexes ( 4 and 5 , respectively) were found to exhibit moderate selectivity for catalytic dimerization of ethylene to butenes over tri‐ or tetramerization. Complex 8 is an effective catalyst of both the commonly encountered “click” reaction and amine arylation chemistries. Complexes 6 and 9 were found to be excellent catalysts for Friedel‐Crafts alkylation and Suzuki‐Miyaura coupling, respectively.
