“…Finally, there are even fewer pincer-type analogues of these complexes. Thus, the first fluoride derivative of a pincer complex of nickel, (PCP t-Bu )NiF, was reported in 2011 by Peruzzini's group, 31 and Caḿpora's group reported the analogous PCP i-Pr complex in 2012; 24 This paucity of data on (pincer)NiF and (pincer)NiCF 3 species is somewhat surprising given the practical importance of fluorination methodologies and the documented reactivities of pincer-Ni complexes in diverse catalytic transformations, including: cyanomethylation, 33 hydrosilylation, 34 CO 2 reduction; 35 Kumada, 36 Suzuki−Miyaura, 37 and Mizoroki−Heck coupling; 38 Zn-mediated homocoupling; 39 electrocatalytic hydrogen production; 40 ethylene polymerization, 41 Michaeltype hydroamination, 42 hydroalkoxylation 42b,c,43 and C−C bond formation; 38,44 and Kharasch addition. 42a,45 The intense interest in pincer complexes of nickel is also due to their ease of synthesis, enhanced thermal stabilities and diverse reactivities compared to analogous complexes based on nonchelating ligands, and the relative abundance of nickel.…”
