说明

應用

Potassium tert-pentoxide solution has been used as a base to synthesize [RuClPh(CO)(H₂IMes)(PCy₃)] from second-generation Grubbs metathesis catalyst, [RuCl₂(=CHPh)(H₂IMes)(PCy₃)], (where H₂IMes is 1,3-dimethyl-4,5-dihydroimidazol-2-ylidene and PCy₃ is tricyclohexylphosphine) and benzyl alcohol. This complex is a solid, air-stable and highly active isomerization catalyst.

注意

可能结晶；可在加热到大约30°C 时重新溶解
