AbstractThe cis- and trans-potassium bis(oxalato)diaquochromates(III) have been studied towards their catalytic activity for the 2-chloroallyl alcohol oligomerization. The geometric isomerism effect on the oligomerization products under mild reaction conditions has been investigated. The molecular masses and tactic structures of obtained poly(2-chloroallyl alcohols) have been compared and analyzed. The mechanisms of oligomerization processes have been proposed. It has been proven that two studied complexes – cis-$$\hbox {K}[\hbox {Cr}(\hbox {C}_{2}\hbox {O}_{4})_{2}(\hbox {OH}_{2})_{2}]$$K[Cr(C2O4)2(OH2)2] and trans-$$\hbox {K}[\hbox {Cr}(\hbox {C}_{2}\hbox {O}_{4})_{2}(\hbox {OH}_{2})_{2}]\cdot \hbox {3H}_{2}\hbox {O}$$K[Cr(C2O4)2(OH2)2]·3H2O are highly active catalysts for the oligomerization of the beta-olefin derivative.Graphical AbstractSYNOPSIS: The investigations show the catalytic activity of cis- and trans-potassium bis(oxalato)diaquochromates(III) for the 2-chloroallyl alcohol oligomerization. The geometric isomerism effect in the bis(oxalato)diaquochromates(III) has been analyzed for the values of the catalytic activity of the synthesized complexes and the identity of the oligomerization products.
