Lj. Morris et al., Photo-induced tautomerisation of methyltrioxorhenium(VII): the intermediate in olefin metathesis?, CHEM COMMUN, (1), 2000, pp. 67-68
Matrix-isolated [CH3ReO3] tautomerises to [H2C=Re(O)(2)OH] under the influe
nce of UV light; the carbene has been characterised in its normal and H-2-
and C-13-enriched isotopic forms by its IR spectrum with results well repli
cated by quantum chemical calculations.
