Derivatives
Although monomeric oxoboranes have not been isolated, derivatives have been described.
A
Lewis acid-stabilized adduct of an oxoborane is (NacNacB=O.AlCl3.[3] In this compound the oxygen atom is coordinated to aluminium chloride. The BO bond length is 130 pm (compare to 136 pm in regular boronic acids). Related systems are known.[4]
In trans-[(Cy3P)2PtBr(BO)], platinum is coordinated to the BO unit.[5] In this compound the BO bond length is 120 picometers.
