Deprotonation of the diphenylphosphine ligand of [CpMo(CO)2(PPh2H)(COR)] (Cp=η5-C5H5, R=Me, Et) with DBU (DBU=1,8-diazabicyclo[5.4.0]undec-7-ene) at -78°C followed by treatment with R'I(R'=Me, Et) leads to the substituted phosphine acyl complexes [CpMo(CO)2(PPh2R')(COR)];If the deprotonation is carried out at room temperature, however, migration of the acyl group to the phosphorus atom occurs to give the acylphosphine alkyl complexe [CpMo(CO)2(PPh2COR)(R')] after alkylation with R'I.
