The m olecule is dim eric and centrosym m etric w ith an planar four-membered [S iN ]2 ring containing trigonal-bipyram idal pentacoordinate silicon and trigonal nitrogen. Significant differences are observed in th e bond len gth s from silicon to its equatorial and axial ligands: S i-N eq 1.736(4), S i-N ax 1.857(4), S i-F eq 1.606(4) and 1.607(3), S i-F ax 1.668(3) Ä.

 Title    Photochemische Telomerisation von Äthylen mit Malonsäurediäthylester  
 Abstract    Under the influence of UV light (HPK 125, Philips) and in presence of diethylketone, benzophenone or acetophenone ethylene and malonic acid diethylester telomerize to give even-numbered n-alkyl-n-butylmalonic acid diethyl esters, which are formed by an 1,5-rearrangement. Low pressure of ethylene favours the rearrangement reaction and the production of short-chained telomers. High concentration of the forementioned ketones effects the reversibility of H-abstraction, which leads to low overall yields, high yields of n-butylmalonic acid diethylester and low yields of telomers produced by rearrangement reactions. The reversibility of the H-abstraction depends upon the applicated ketone.
