Photolytic CH activation and dehydrogenation of alkanes at cyclopentadienyl iridium complexes in a perfluorinated solvent
The fluorinated complex [(Cp f )Ir(CO) 2 ] ( 2 ) [Cp f = C 5 H 4 (CH 2 ) 2 (CF 2 ) 5 CF 3 ] serves as a precursor for the photolytic activation of CH bonds in alkanes to give [(Cp f )Ir(CH 3 )(H)(CO)] ( 3 ), [(Cp f )Ir(C 5 H 9 )(H)(CO)] ( 4 ), [(Cp f )Ir(C 6 H 11 )(H)(CO)] ( 5 ) or [(Cp f )Ir(C 8 H...
