An easy synthesis of linear cyclic 2-unsaturated boronates via organometallic reagents has been achieved. The final structure of the carbon framework is related to the tetracoordinated intermediate. Intermolecular rearrangement, disproportionation and reactions with carbonyl compounds have been studied.

from the reaction of dioxaborolanes and dioxaborinanes with either organolithium or organomagnesium reagents are investigated along with their subsequent use in the palladium cross coupling reaction. The intrinsic stability of these cyclic esters contributes to their facile reaction with both lithium and magnesium nucleophiles at mild and safe conditions. We have found that many of the reactions proceed
