Fine Tuning the Si-Sn Bond: Transmetalations Forming Either Trialkylstannyl or Trialkylsilyl Higher Order Cyanocuprates

Article abstract of DOI:10.1021/jo00282a001

Depending upon the nature of the alkyl groups attached to silicon and tin in R3Sn-SiR'R2", compounds of this type undergo ligand exchange upon treatment with a higher order cuprate to afford trialkylstannyl or trialkylsilyl mixed cuprates which participate in substitution, conjugate addition, and metalcupration reactions.
