Diethyl 2-[(N-benzyl-N-methylamino)(phenyl)methyl]propanedioate
In the title compound, C(22)H(27)NO(4), the mean planes of the two benzene rings form a dihedral angle of 73.54 (13)°. One of the methyl groups is disordered over two sites, with site occupation factors of 0.47 (15) and 0.53 (15). The crystal packing is controlled by van der Waals forces and a possible C-H⋯O inter-action, forming a chain running parallel to the a axis.

The asymmetric unit of the title compound, C(18)H(22)N(2)O(3)S, contains two mol-ecules, exhibiting similar conformations [C-S-N-C torsion angles of -82.2 (2) and -70.4 (2)°, and dihedral angles between the mean planes of the aromatic rings of 56.6 (6) and 51.6 (6)° in mol-ecules I and II, respectively]. However, the two independent mol-ecules show distinctly different hydrogen-bonding patterns...

In the title compound, C(14)H(13)NO(2), the mean planes through the benzyl and 2-hydoxybenzamide units make a dihedral angle of 68.81 (7)°. There is an intra-molecular O-H⋯O hydrogen bond involving the carbonyl O atom and the 2-hydr-oxy substituent. In the crystal structure, N-H⋯O hydrogen bonds link symmetry-related mol-ecules into one-dimensional chains extending along the a-axis direction. T...
متن کاملN-Benzyl-2-propynamide
Pale-yellow crystals of the title compound, C(10)H(9)NO, have been obtained by the reaction of benzyl-amine and methyl propiolate. Weak inter-molecular hydrogen bonding is observed between acetyl-enic H and carbonyl O atoms. The crystal packing is stabilized by these C-H⋯O and by N-H⋯O inter-molecular hydrogen-bonding inter-actions.
متن کاملN-Benzyl-N-(2-methoxyphenyl)benzenesulfonamide
In the title mol-ecule, C(20)H(19)NO(3)S, the dihedral angle between the phenyl rings is 48.93 (18)°, and they make dihedral angles of 38.37 (17) and 86.50 (19)° with the benzene ring. A weak intra-molecular C-H⋯O inter-action might stabilize the mol-ecular conformation. In the crystal, weak π-π stacking inter-actions between the benzene rings [centroid-centroid distance = 3.774 (2) Å] may help...
