Dipyrrolidylmethane, CH2(pyr)2, and dipiperidylmethane, CH2(pip)2, are synthesized via the condensation of their respective secondary amine precursors and dichloromethane at room temperature in the absence of light. Their use as chelating ligands is shown by the isolation and complete characterization of [CH2(pyr)2]Mo(CO)4 and [CH2(pip)2]Mo(CO)4 complexes. X-ray analysis reveals the methylene bis(cycloamines) to possess a sharp bite angle between 61掳 and 63掳 and a strong steric impact on the surrounding carbonyl ligands as a result of their ring conformations.
