Arylmalononitriles are prepared in good yields using a palladium-catalysed coupling reaction between aryl halides and malononitrile.

Incorporation of a redox-passive bridge affords three identical redox systems in the triskelion-shaped, carbon-rich, polyvinylidenemetal complex 1. The complex was isolated from the activation of the tripodal polyyne 1,3,5-(HC≡CC H C≡C) C H with [RuCl ({(Ph P) C H } ] and further converted into polyynylmetal complexes and a triple ferrocenyl-substituted ruthenium complex.

CTV derivatives with aromatic pendants were synthesized and their inclusion abilities for C60 and C70 were examined by UV spectroscopy. CTV derivative with three N-methylpyrrole pendants showed the highest association constant for C60 (48000 dm3mol−1 in benzene). The structure of inclusion complex for C60 with CTV derivative which has six benzoyl pendants has been determined by single-crystal X-ray diffraction.
