Ring opening and coordination behavior of mono benzoxazine based N-capped amino bis(disubstitutedphenol) and bis(benzoxazine) based 1,2-bis(6,8-disubstitutedbenzo[e][1,3]oxazin-3(4H)-yl)ethane in the presence of precursors VO(OEt)3, [MoVIO2(acac)2] and [WVIO2(acac)2] have been studied. Catalytic potential of the resulting complexes has been explored for the multicomponent (aromatic aldehyde, ethyl
