Reactions of Ar′CrCrAr′ with N2O or N3(1-Ad): complete cleavage of the Cr–Cr quintuple interaction

Abstract

Reaction of Ar'CrCrAr' (Ar' = C(6)H(3)-2,6-(C(6)H(3)-2,6-Pr(i)(2))(2)) with heterocumulene reagents N(2)O or N(3)(1-Ad) resulted in Ar'Cr(micro-O)(2)Cr(O)Ar' or Ar'Cr(micro(2):eta(1),eta(3)-N(3)(1-Ad))CrAr' which have no metal-metal bonding.
