摘要：

By varying the temperature, tBuCP reacts in the presence of η4‐butadiene(η8‐cyclooctatetraene)hafnium complexes to give different cyclooligomers. Thus, the triphosphabenzene 1 is formed at ‐78 °C and the dewar‐triphosphabenzene 2 at 0 °C. Both compounds are initially bound to the complex and can be liberated with hexachloroethane in a redox reaction. Compounds 1 and 2 are the first compounds of these classes of substances. Cyclodimers or cyclotetramers are obtained at higher temperature. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
