Abstract
|
|
|
|
2-Furyltriisopropoxytitanium was synthesized in situ through transmetallation of 2-furyllithium with chlorotitaniumtriisopropoxide. The compound could be isolated at room temperature and preserved at -10℃ for several weeks. The reactivity of 2-furyltriisopropoxytitanium to carbonyl compounds proved to be high. A complete aldehydeselectivity was observed in competition reactions of 2-furyltriisopropoxytitanium with a 1 : 1 mixture of aldehyde and ketone. In competition reactions of 2-furyltriisopropoxytitanium with a 1: 1 mixture of ketone and ketone, the degree of ketone / ketone discrimination was substantial. In the reaction of 2-furyltriisopropoxytitanium to ketone-ester function, the reagent was solely reacted with the ketone function.
