  The Synthesis of [2-2H1]Thiirane-1-oxide and [2,2-2H2]Thiirane-1-oxide and the Diastereoselective Infrared Laser Chemistry of [2-2H1]Thiirane-1-oxide

  摘要：

  We report the synthesis of the title compounds CH2CHDSO and CH2CD2SO and their characterization by infrared spectroscopy. The monodeuterated species occurs in two isotopically diastereomeric forms with the D atom either cis or trans oriented to the O atom, The SO infrared chromophore in these diastereomers has a strong absorption centered near 1114 and 1116 cm(-1), respectively, with an integrated band strength G = 2.8 pm(2), which renders it very suitable for infrared multiphoton excitation with a CO2 laser, leading to the laser chemical dissociation of the reactants into deuterated ethylene and SO((3) Sigma(-)). We have established the first successful laser chemical separation of such a diastereomer pair, with a small but significant separation factor based on the small frequency difference of the v(4) (SO stretching) fundamental mentioned above; the analysis used high-resolution FTIR spectroscopy in the region of the Q branches of v(4). Our results are discussed in relation to various aspects of stereochemical reaction dynamics in chiral and achiral sulfoxides.
