From Dimethylamine to Pyrrolidine: The Development of an Improved Nickel Pincer Complex for Cross-Coupling of Nonactivated Secondary Alkyl Halides

Replacement of a dimethyl amino group of the amidobis(amine) nickel(II) pincer complex (1), [(MeN2N)Ni-Cl], by a pyrrolidino group resulted in a new nickel(II) pincer complex (2), [(PyrNMeNN)Ni-Cl]. Complex 2 is an efficient catalyst for Kumada and Suzuki-Miyaura cross-coupling of nonactivated secondary alkyl halides, while complex 1 is largely inactive. The significant activity difference is tentatively attributed to a minimal structural difference, which leads to a more hemilabile ligand.
Generation of α,β-unsaturated platinum carbenes from homopropargylic alcohols: Rearrangements to polysubstituted furans
Allegretti, Paul A.,Ferreira, Eric M.
, p. 5924 - 5927 (2011/12/16)
A number of diversely substituted furans are synthesized via a cycloisomerization process that goes through a unique metal carbene species. Both ligand structure and the nature of the leaving group are evaluated. The characteristics of the carbene intermediate can be modulated, resulting in highly selective hydrogen or silicon group migrations.
Synthesis and Characterisation of some 1,4,8,11,15,18,22,25-Octa-alkyl- and 1,4,8,11,15,18-Hexa-alkyl-22,25-bis(carboxypropyl)phthalocyanines

A series of 3,6-dialkylphthalonitriles and 3,6-bis(4,4,4-trimethoxybutyl)phthalonitrile have been prepared via Diels-Alder reactions of 2,5-disubstituted furans or thiophene 1,1-dioxides with fumaronitrile.The phthalonitriles were converted into the title phthalocyanines as metal-free and copper(II) derivatives.The macrocycles were characterised using 1H NMR and optical spectroscopy, and fastatom bombardment spectrometry.Certain examples exhibit discotic liquid crystal behaviour.
