“…Bond distances and bond angles show good agreement with equivalent parameters reported for related structures (BERNSTEIN;BACHECHI et al;FERGUSON et al 1990), except those involving the disordered atom. The bond lengths and bond angles involving the disordered atom are unreliable.…”

Crystal structure of R( -)-1-Tosyl-2-methylpyrrolidineThe crystal structure of R( -)-1-tosyl-2-methylpyrrolidine has been determined by X-ray structure analysis. The compound crystallizes in the monoclinic space group P2, with cell parameters a = 7.858( l), b = 14.929(6), c = 11.128(1) A, p = 105.42(1) ' . The structure has been solved by direct methods and relined to R = 0.046. There are two crystallographically independent molecules A and B in the asymmetric unit. The pyrrolidine ring of molecule A is disordered with atom C4 occupying two possible sites. The S atom has a distorted tetrahedral coordination in both the molecules. Two bifurcated hydrogen bonds are observed. Molecules are held together by hydrogen bonds.GUPTA et al.: Structure of R( -)-l-Tosyl-2-methylpyrrolidine taken as observed. During data collection three strong reflections (2 1 z , J 0 1,2 1 3) measured after every 55 reflections showed that the crystal was stable to X-rays. Data were corrected for Lorentz and polarization effects. The crystallographic data are summarized In Table 1.

“…Therefore, we have undertaken an X-ray structural investigation of these compounds in order to understand their different behaviour toward hydrazines. In this paper, the crystal structure of 2-acetyl-3-aminobenzofuran is described; that of the N-ptoluenesulfonyl derivative has been reported previously (Bachechi, Coiro, Gatta, Settimj & Delfini, 1988).…”

“…The N--C(3) and C=O bond lengths compare with the dimensions usually found for the amide group (Pauling, 1980) and they are indicative of delocalization and involvement in a conjugate system which includes the aminobenzofuran moiety and the C=O group. With respect to the N-toluenesulfonyl derivative (Bachechi, Coiro, Gatta, Settimj & Delfini, 1988), in which one H atom of the amino group is substituted by a p-toluensulfonyl group, the title compound is less planar, the plane through the acetyl group forming an angle of about 8 ° with the plane of the benzofuran moiety (about 0 ° in the N-toluenesulfonyl derivative).…”

“…Since only the N-p-toluenesulfonylbenzofurans gave hydrazones in good yield, Xray structural investigations on the starting compounds and products of this preliminary synthesis were carried out in order to gain a better understanding of the mechanism of the reaction with hydrazines. So far, the structures of the starting compounds (1) (Bachechi, Coiro, Gatta, Settimj & Delfini, 1988) and (2) (Bachechi, Coiro, Delfini & Settimj, 1988), and of the product The structure consists of two planar moieties, the benzofuran and the S-aryl systems, which form an angle of 65.6(1) ° with one another. The benzofuran moiety can be considered planar as is the case in the corresponding starting compound, (1).…”
