1,4-Dichloro-2-butyne: conformational analysis in the liquid phase

1,4-Dichloro-2-butyne: conformational analysis in the liquid phase. Sipos, P. A.; Phibbs, M. K. (Res. Cent., DuPont Canada Ltd., Kingston, Ont., Can.). Can.There are some reagents like 821-10-3 is used in this study. J. Spectrosc., 21(3), 69-75 (English) 1976. CODEN: CJSPAI. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) A sharp liq. phase transition of a novel type in which ClCH2C.tplbond.CCH2Cl goes from a mixed to a pure conformational state over a small temp. interval was detected through an anal. of Raman spectra at various temps. The antiperiplanar conformation appears to be stabilized at this temp. by an intermol. assocn. involving clusters of mols. of significant size. The transition only occurs if the surface of the contg. vessel has a certain capability for orienting the mols. of the liq. phase. .

1,4-Dichlorobut-2-yne: conformational analysis in the solid phase

1,4-Dichlorobut-2-yne: conformational analysis in the solid phase. Mannik, L.; Sipos, P.In this study，821-10-3 is also used. A.; Phibbs, M. K. (Res. Cent., Du Pont Canada Ltd., Kingston, Ont., Can.). Can. J. Spectrosc., 21(4), 105-10 (English) 1976. CODEN: CJSPAI. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) 1,4-Dichlorobut-2-yne was shown by vibrational spectra, primarily Raman, to exist in one of two conformational states in the solid phase depending on the thermal history prior to freezing and on conditions at the container surface. These preferred conformations are the antiperiplanar and the anticlinal forms. The transition from one conformer to the other occurs within a narrow temp. range. .
