Abstract
The reaction of monoaza-15-crown-5 1 with bromoalkylphosphine oxides 2 and diphenyl-vinylphosphine oxide Zed to a new type of lariat ethers (3a-d), on e member of which (3a) was deoxygenated to the corresponding phosphine (4). The substituent at the nitrogen atom had a great impact on the extraction ability of the azacrown. (C) 1999 John Wiley & Sons, Inc.
