N2 - Germylyne complex Cp(CO)2W/Ge{C(SiMe3)3} (1) reacted with two molecules of RC(O)CH=CH2 (R = Me, Et) to give η3-allyl complexes, in which an oxagermacyclopentene framework was bound to an η3-allyl ligand through an oxygen atom. In the reaction with α-Me-substituted MeC(O)C(Me)=CH2, 1 reacted with only one molecule of the substrate to give another type of η3- allyl complex, in which a five-membered oxagermacyclopentenyl ring was coordinated to the W center in an η3 fashion. Both reactions resulted in unprecedented complete cleavage of a W/Ge triple bond.
