Abstract Symmetrical anhydrides of hydroxycarbene complexes of manganese and rhenium, [π-C5H5(CO)2MC(R)]2O, (M = Mn, Re) are prepared by reaction of cationic carbyne complexes [π-C5H5(CO)2MCR]BX4 with the corresponding metal carbonyl acylates Li[π-C5H5(CO)2MC(O)R]. [π-C5H5(CO)2MnC(C6H5)]2O is also obtained by controlled hydrolysis of π-C5H5(CO)2MnCX(Br)Ce6H5. The new complexes are characterized spectroscopically and by an X-ray structure analysis of [π-C5H5(CO)2MnC(C6H5)2O.
