Die Konformation substituierter Trimethylensulfite

Abstract: Eingegangen a m 27. Februar 1970Aus den IR-und NMR-Spektren sowie den Dipolmomenten wird abgeleitet, da8 in Losung vorliegen: 2.2-Dimethyl-trimethylensulfit (2) und cis-1.3-Dimethyl-trimethylen-trans-sulfit (3a) als Sessel-Konformation mit axialer S =0-Gruppe, cis-1.3-Dimethyltrimethylen-cissulfit (3 b) entsprechend mit aquatorialer S = 0-Gruppe, trans-1.3-Dimethyl-trimethylentrans-sulfit (3c) aber als Konformationsgleichgewicht, an dem Twist-Konformationen beteiligt sind. Conformation of Substituted Trimethyl… Show more

“…spectra that a conformational mixture of chair forms (S=O axial and S=O equatorial) was present with S=O axial predominating. From spectral studies and dipole moments, Wucherpfennig (16) proposed a mixture of twist and perhaps chair forms. A previous spectral study (17) of the analogous racemic 4,6-diisopropyl trimethylene sulfite was in favor of the twist form.…”
