R2Si=XRn systems



 Hi,
 I am presently trying to get an overview of the literature concerned
 with the class of systems containing a formal double bond Si=X, where
 X are 2nd and 3rd row main group elements. Of particular interest are
 calculations concerned with relative stabilities.
 I am aware of the paper by Schleyer and Kost, J. Am. Chem. Soc. 1988,
 110, p2105 and older literature. Not having access to online-CAS makes
 literature surveys a bit slow, thus this request.
 Please respond to me directly, and, if you are interested in a summary,
 send a note as well  - I'll summmarize to the net, given enough interest.
 		thanks in advance
