Synthesis, characterisation and catalytic investigation of a new type of PC(sp(3))P pincer Pd(II) complex
(2002) In Journal of the Chemical Society. Dalton Transactions p.1396-1400- Abstract
- The diphosphine cis-1,3-bis[(di-tert-butylphosphino)methyl]cyclohexane (2) has been synthesised and its complexation in palladium chemistry has been investigated. Ligand 2 is capable of tricoordination, for instance as demonstrated by an X-ray crystal structure determination of the complex [Pd(2)I], and it is a rare example of a PC(sp(3))P pincer ligand. A catalytic study of the Heck reaction revealed that the bis-chelated complex [Pd(2)(CO2CF3)] is a highly active, air-stable precatalyst in the olefination of iodo- and bromo-benzenes. It is evident that, in comparison with the analogous aromatic PC(sp(2))P system, by switching the hybridisation of the central carbon donor atom from sp(2) to sp(3) improvement in terms of catalytic activity...
