In this paper, the chemical Functionalization of Carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. Phosphorus Ylides are important compound in organic chemistry. At first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...

The triphenyl-methyl group in the title compound, C(28)H(23)IO(2)S, has the methine carbon slightly flattened out [ΣC(phen-yl)-C-C(phen-yl) = 332.8 (6) °]. The -C-O-C-C-S- chain connecting the triphenyl-methyl group and the aromatic ring adopts an extended zigzag conformation, these five atoms being approximately co-planar (r.m.s. deviation 0.260 Å).

The title compound, C(44)H(35)NS, is a derivative of amino-thio-phenol and possesses a protected S-triphenyl-methyl thio-ether and an N-triphenyl-methyl-amine functional group. The trityl groups show an anti orientation, with C-C-N-C and C-C-S-C torsion angles of -151.0 (3) and -105.3 (2)°, respectively. There is an intra-molecular N-H⋯S hydrogen bond.

The methine C atom of the triphenyl-methyl group in the title compound, C(28)H(23)IO(2)S, is slightly flattened out [ΣC(phen-yl)-C-C(phen-yl) = 335.6 (5)°]. The -C-O-C-C-S- chain connecting the triphenyl-methyl group and the aromatic ring adopts an extended zigzag conformation, these five atoms lying on an approximate plane (r.m.s. deviation = 0.120 Å).
