Formation of trisubstituted buta-1,3-dienes and α,β-unsaturated ketones <i>via</i> the reaction of functionalized vinyl phosphates and vinyl phosphordiamidates with organometallic reagents
ester functional group with organometallic reagents. We found that the functionalized vinyl phosphates were smoothly converted into tri- and tetrasubstituted buta-1,3-dienes via the reaction with aryllithium reagents. Moreover, the vinyl phosphordiamidates were converted into α,β-unsaturated ketones using Grignard reagents. Based on the performed experiments, we proposed a reaction mechanism, which was
