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.
