摘要：

Peterson olefination of the sterically hindered cyclopropenones 1 with the lithium phosphides 2 yields the so far unknown phophatriafulvenes 3 and 4, which possess inverse electron densities. They are characterized by transition metal complex formation (--> 7, 8). Acylation of 3a with the carboxylic acid chlorides 11 leads to a great variety of P-acylphosphatriafulvenes 13a-s. They partly dimerize under formation of the 1,3-diphosphacyclobutanes 13 reversible 14.
