چکیده
The title compound, C(19)H(11)NO, is stabilized by one intra-molecular C-H⋯O hydrogen bond. The compound can be synthesized in good yield (49%), by transformation of functional groups [starting with 5-(fluoren-9-ylidenemeth-yl)furan-2-carbaldehyde]. The flourene and furan ring systems are nearly coplanar, with a dihedral angle of 6.36 (7)°.

The title mol-ecule, C24H25NOSi, is a hydrolysis product of the reaction between 9-tri-methyl-silyfluorenyl lithium and 2-meth-oxy-benzo-nitrile. The fluorene ring system is substanti-ally planar, with an r.m.s. deviation of 0.0288 Å from the best-fit plane through its 13 C atoms. This plane forms a dihedral angle of 58.07 (7)° with the 2-meth-oxy-benzyl-amine ring plane. In the crystal, mol-ec...
