摘要：

1,3-Di(tert-butyl)-2,4-bis[2,4,6-tri(tert-butyl)phenyl]-1,3-diphosphacyclobutane-2,4-diyl was formed from [2,4,6-tri(tert-butyl)phenyl]phosphaacetylene and t-BuLi. In addition, the X-ray diffraction analysis was carried out, together with theoretical calculations of the structure and NMR data.
