Popis:	Detailed 1H-, 13C-, and 31P NMR studies of 1-t-butyl-3-methyl-2,4-bis(2,4,6-tri-t-butylphenyl)-1,3-diphosphacyclobutane-2,4-diyl reveal several unusual coupling constants together with recognition of the diastereotopicity of the compound. These new data support an uncommon phosphorus-containing molecular structure for the ring system. © 2011 Wiley Periodicals, Inc.
