Dehydrogenation of alkanes catalyzed by an iridium phosphinito PCP pincer complex

Recent Advances on the Chemistry of POCOP–Nickel Pincer Compounds

“…Following these reports, the synthesis of the first POCOP-iridium species was done in 2004 [46,47], and the rhodium [48], ruthenium [49,50] conditions in toluene in good yields (Fig. 3).…”

A catalytic synthesis of dialkylamines from alkylamines using neopentyl-substituted PNP pincer–iridium complex

“…Among them, bulky and electron-rich pincer/Ir system has been utilized to dehydrogenation of alkanes [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The key to succeed this unique transformation may be due to remarkable thermodynamic stability of pincer-ligated metal complex, resulted from tight coordination to the metal center.…”

Synthesis of a new class of unsymmetrical PCP′ pincer ligands and their palladium (II) complexes: X-ray structure determination of PdCl{C6H3-2-CH2PPh2-6-CH2PBut2}

“…Complexes of these tridenate pincer ligands are sufficiently robust to withstand the elevated temperatures at which the activation of aliphatic C-H and C-Cl bonds become thermodynamically favorable. Thus, these complexes have been found to have remarkable catalytic activity in aliphatic dehydrogenation [2][3][4] and C-C coupling reactions [5][6][7][8].…”

“…We have explored the reactivity of the palladium and 0022-328X/$ -see front matter Ó 2004 Elsevier B.V. All rights reserved. doi:10.1016/j.jorganchem.2004.05.009 iridium derivatives of these novel ligands, successfully utilizing them as catalysts for Heck couplings [6,7], aliphatic dehydrogenations [4], allylic alkylation [10], and Sonagashira couplings [8]. As part of our effort to create novel PCP pincer systems in which both the electronic and steric properties may be easily modulated, we have designed a novel synthetic route for the high yield synthesis of unsymmetrical phosphino PCP 0 pincer type ligands (Scheme 2e).…”
