1,3-Bis(2,6-diisopropyl­phen­yl)imidazolidinium tetra­phenyl­borate dichloro­methane disolvate

The title compound, C(27)H(39)N(2) (+)·C(24)H(20)B(−)·2CH(2)Cl(2), is the first reported imidazolidinium cation with the sterically demanding 2,6-diisopropyl­phenyl groups in the 1,3-positions. The crystal structure is stabilized by weak inter­molecular C—H⋯π(arene) inter­actions. Due to the bulky n...

Sumario:The title compound, C(27)H(39)N(2) (+)·C(24)H(20)B(−)·2CH(2)Cl(2), is the first reported imidazolidinium cation with the sterically demanding 2,6-diisopropyl­phenyl groups in the 1,3-positions. The crystal structure is stabilized by weak inter­molecular C—H⋯π(arene) inter­actions. Due to the bulky nature of both the flanking 2,6-diisopropyl­phenyl substituents and the tetra­phenyl­borate counter-ion, anion inter­actions with the imidazolidinium H atom in the 2-position are not observed, also a first for this class of ortho-alkyl-substituted Arduengo-type carbene precursors.
