N-C bond formation between two anilines coordinated to a ruthenium center in -form affording a 3,5-cyclohexadiene-1,2-diimine moiety
Ruthenium complexes containing two anilines or its derivatives, cis -[Ru II (NH 2 C 6 H 5 ) 2 (bpy) 2 ] 2+ ([ 1 ] 2+ ) and cis -[Ru II (NH 2 C 6 H 4 (4-CH 3 )) 2 (bpy) 2 ] 2+ ([ 2 ] 2+ ), were oxidized by four molar equivalents of (NH 4 ) 4 [Ce IV (SO 4 ) 4 ]·2H 2 O to give N 1 -phenylcyclohexa-3,5-...
