Abstract
Pentamethylcyclopentadienyltrichlorosilane reacts with Li[Al(PH2)(4)] to give the stable ,3-diphosphino-2,4-diphospha-1,3-disilacyclobutane 4. Treatment of 4 with Lithium alkyls affords the Lithium phosphide 5 via regiospecific metalation of a ring phosphorus atom, and reaction w ith t-Bu(2)Hg proceeds via oxidative P-P bond formation to yield the - disila-2,3,5,6-tetraphospha-bicyclo[2,1,1]-hexane 6. Cleavage of penta methylcyclopentadiene is observed during thermolysis of 4 at 200 degre es C. 4-6 were characterised by NMR-spectroscopy, and 4 by an addition al crystal structure determination.
