Zhu H, Chai J, Ma Q, Jancik V, Roesky HW, Fan H, Herbst-Irmer R: A seven-membered aluminum sulfur allenyl heterocycle arising from the conversion of an aluminacyclopropene with CS2. J Am Chem Soc. 2004 Aug 25;126(33):10194-5.
The reaction of an aluminacyclopropene LAl [eta2-C2 (SiMe3) 2] (1, L = HC (CMeNAr) 2, Ar = 2,6-iPr2C6H3) with CS2 in the temperature range from -78 degrees C to room temperature affords the first seven-membered aluminum sulfur-containing heterocyclic compound [LAl] 2 (mu-S)[eta2-SC (SiMe3)=C=C (SiMe3)] (2) bearing an allenyl group. The structural characterization of 2 and the analogous compound LAl [OC (O) C2 (SiMe3) 2] (3) of the proposed intermediate A and the variable-temperature 1H NMR kinetic study of this reaction may give a better understanding on this unusual conversion. |
