The reaction of monoaza-15-crown-5 1 with bromoalkylphosphine oxides 2 and diphenylvinylphosphine oxide led to a new type of lariat ethers (3a-d), one member of which (3a) was deoxygenated to the corresponding phosphine (4). The substituent at the nitrogen atom had a great impact on the extraction a
