The synthesis is carried out under nitrogen and dry, desoxigenated MeCN is used.
(NEt4)[Re(CO)3Br3] (0.078 g, 0.1 mmol) and p-Ethylacetoxy-oxacalix[3]aren
(0.062 g, 0.1 mmol) are suspended in 2 mL acetonitril. 1,8-
Diazabicyclo[5.4.0]undec-7-ene (DBU) (0.046 g, 0.3 mmol) is added and the
resulting solution is heated for 5.5 hours at 85 deg C. After cooling to room
temperature the solution is filtered and stored over night at room temperature.
Some small, colourless crystals grew over night.
