Optical Activity in Silicon-Transition-Metal Compounds

Optical Activity in Silicon-Transition-Metal Compounds 

The synthesis of a number of compounds of the type R R R SiM(L)B, with a chiral silicon atom, has made it possible to examine the stereochemistry of reactions of silicon in some detail. Table XXII shows that compounds with silicon linked to Mn, Fe, Co, and Pt have been studied. 

Compound (LXVIII) in entries 1-6 is readily made by the oxidative addition-elimination reaction  

It is assumed, in common with other reactions involving metal insertion into Si-H bonds (see below), that this reaction proceeds with retention of configuration at silicon. 

Compound (LXIX) results from the reaction of the appropriate chlorosilane with [Fe(CO)2(i7 -CsHs)] anions (91, 92, 123) such reactions proceed with inversion of configuration (406)
