摘要：

4-Bromophenyldi(3-methylindol-2-yl)methane (2) and 2-methoxyphenyldi(3-methylindol-2-yl) methane (3) were prepared by sulfuric-acid-catalyzed reactions of 3-methylindole with 4-bromobenzaldehyde and o-anisaldehyde, respectively. Di(3-methylindol-2yl)phenylmethane (1) and tri(3-methylindol-2-yl)methane (4) were similarly prepared as described previously. Spectroscopic data (H-1, C-13 NMR) and the X-ray crystal structures for 1.C2H5OH and 2-4 are reported. The molecular structure of 1.C2H5OH shows hydrogen bonding of both indolyl NH protons to the oxygen of an ethanol molecule. Crystal data for 1.C2H5OH.Orthorhombic, Pca2(1), a = 23.9782(17) Angstrom, b = 8.4437(7) Angstrom, c = 11.3029(9) Angstrom, V = 2288.4(3) Angstrom(3), R-1 = 0.0597. Crystal data for 2.Orthorhombic, P2(1)2(1)2(1), a = 8.911(3) Angstrom, b = 9.584(4) Angstrom, c = 24.040(11) Angstrom, V = 2053.0(14) Angstrom(3), R1 = 0.0454. Crystal data for 3.Monoclinic, P2(1)/c, a = 9.737(2) Angstrom, b = 25.035(6) Angstrom, c = 9.359(2) Angstrom, beta = 114.853(4)degrees, V = 2070.2(8) Angstrom(3), R-1 = 0.0511. Crystal data for 4.Trigonal, R3, a = 14.2214(10) Angstrom, c = 9.6190(10) Angstrom, V = 1684.8(2) Angstrom(3), R-1 = 0.0425.
