Tanini, Damiano,Angeli, Andrea,Capperucci, Antonella
, p. 156 - 158 (2016/02/18)
Reaction of bis(trimethylsilyl)sulfide (HMDST) with aldehydes can be efficiently carried out in various ionic liquids, under CoCl2.6H2O or TfOTMF catalysis, leading to the formation of thioaldehydes, which are trapped as Diels-Alder

The pentacarbonyl(thioaldehyde), -(selenoaldehyde), and -(selenoketone) complexes (CO)5M (I) (M = Cr: X = S, R = H (a); M = W: X = S, R = H (b); X = Se, R = H (c); X = Se, R = Ph (d)) react with 2,3-dimethyl-1,3-butadiene by -cycloaddition to give the metal-coordinated thia- and selenacycles, (CO)5M (IIIa-d).The Structure of IIId was established by an X-ray diffraction study.The reactions of Ia with 2-methyl-1,3-butadien (IV) and of Ia and Ib with trans-penta-1,3-diene (VI) are regioselective.The cycloaddition of IV to Ia yields the two isomers (CO)5Cr or (CO)5M in the ratio 2.4/1 (M = Cr) or 3/1 (M = W), respectively.The thiacycle can be cleaved from the metal intact by oxidation of IIIa with (NH4)2 in acetone.
