| Abstract: | Abstract Novel P-H-diphosphinoalkanes with pyridyl substituents at the phosphorus atoms have been obtained in good or moderate yields by the interaction of primary 2-pyridyl-phosphine with dichloroalkanes in superbasic medium. The formation of novel 1-(2-pyridyl)-1-phosphacyclopentane together with bis(2-pyridylphosphino)butane was observed as the result of the interaction of 2-pyridylphosphine and 1,4-dichlorobutane under the same reaction conditions. The reaction of the bis(2-pyridylphosphino)alkanes thus obtained with formaldehyde leads to the formation of the corresponding hydroxymethyl derivatives. |
