N2 - Sterically protected 1,2-diary1-3,4-diphosphinidenecyclobutenes were prepared from 3-ary1-2-bromo-1-(2,4,6-tri-t-butylphenyl)-3-(trimethylsiloxy)- l-phosphapropene using t-butyllithium and 1,2-dibromoethane, and the properties of the products, such as 1,2-di(2,2′-bithienyl-5-yl)-3,4- diphosphinidenecyclobutene, were studied. This method is an excellent method for preparing these compounds.
