Catalytic epoxidation of stilbenes with non-peripherally alkyl substituted carbonyl ruthenium phthalocyanine complexes
Enow, Charles A.,Marais, Charlene,Bezuidenhoudt, Barend C.B.
experimental part, p. 403 - 412 (2012/08/07)
A number of novel carbonyl(1,4,8,11,15,18,22,25-octaalkylphthalocyaninato)- ruthenium(II) complexes were prepared by metal insertion with Ru 3(CO)12. The new compounds have been characterized by 1H NMR, 13C NMR, IR, UV-vis and mass spectroscopy. This study demonstrated that this type of complexes and specifically carbonyl(1,4,8,11,15,18,22,25-octahexylphthalo-cyaninato)ruthenium(II) and carbonyl[1,4,8,11,15,18,22,25-octa(2-cyclohexylethyl)phthalocyaninato] -ruthenium(II), exhibit high catalytic activity and stability in the epoxidation of stilbenes with 2,6-dichloropyridine N-oxide as oxidant.
Improved syntheses of high hole mobility phthalocyanines: A case of steric assistance in the cyclo-oligomerisation of phthalonitriles

It has been shown that the base-initiated cyclo-oligomerisation of phthalonitriles is favoured by bulky α-substituents making it possible to obtain the metal-free phthalocyanine directly and in high yield. The phthalocyanine with eight α-isoheptyl substituents gives a high time-of-flight hole mobility of 0.14 cm2·V -1·s-1 within the temperature range of the columnar hexagonal phase, that is 169-189 °C.
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.
