Efficient routes toward activation of gem-chlorofluorocyclopropane-derived (2-fluoroallyl)boronates for allylboration of various ketones including functionalized and low-reactive ones were developed. Increasing the boron electrophilicity by the transformation of a boronate moiety into a borinicester with nBuLi/trifluoroacetic anhydride (TFAA) makes (2-fluoroallyl)boration of acetyl arenes/hetarenes
