Ethyl and isopropyl 4-ferrocenyl-benzoate.
The title compounds, [Fe(C(5)H(5))(C(14)H(13)O(2))] and [Fe(C(5)H(5))(C(15)H(15)O(2))], respectively, contain the ferrocenyl eta(5)(C(5)H(4)) and phenylene -C(6)H(4)- rings in a nearly coplanar arrangement, with interplanar angles of 6.88 (12) and 10.5 (2) degrees, respectively. Molecules of the ethyl ester form dimers through eta(5)(C(5)H(5))C-H...O=C hydrogen bonds, with graph set R(2)(2)(20)...
متن کامل2-Ethyl-3-hydroxy-1-isopropyl-4-pyridone
The title compound, C(10)H(15)NO(2), crystallized with three mol-ecules in the asymmetric unit. These three mol-ecules are quite similar except for slight differences in the torsion angles of the substituents on the ring. The isopropyl C-C-N-C torsion angles (towards the carbon next to the ethyl bound carbon), for example, are -150.63 (11), -126.77 (13) and -138.76 (11)° for mol-ecules A, B and...
متن کاملIsopropyl 4-nitrobenzoate
In the mol-ecule of the title compound, C(10)H(11)NO(4), the nitro group is approximately coplanar with the benzene ring [dihedral angle = 4.57 (10)°], while the carboxyl-ate group is slightly twisted, making an angle of 12.16 (8)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonding and π-π stacking inter-actions [centroid-centroid distances = 3.670 (2) and 3.665 (2) Å] are observed.
متن کاملEthyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxylate
In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.
متن کاملRearrangement Reactions following Electron Impact on Ethyl and Isopropyl Esters
The mass spectra of ethyl and isopropyl propionate and butyrate show rearrangement ions RlCOOH+ and RlC(OH)2+ formed by reactions [a] and [b]: R,COOR2+ --t RiCOOH+ + (R2 H), RlCOOR2+ --t R I C ( O H ) ~ + (R2 213). The mass spectra of ethyl-d2 propionate and butyrate show that both [a] and [b] occur with essentially complete scrambling of the alkoxy hydrogens. For the isopropyl esters the mass ...
