In conclusion, we have shown that the olefination of alkylidenemalonates 1 by 1,l-dimetalloalkanes 2 can ac- commodate a variety of functional groups and afford PO- lyfunctional olefins 3 with fair to excellent 2 stereoselec- tivities. Further studies are currently underway in our laboratories. ...
