Chemical Properties
colorless to slightly yellow liquid
Uses
trans-1,2-Bis(tri-n-butylstannyl)ethylene can be used in versatile vinyl anion synthon: efficiently monotransmetalated by alkyllithium reagents and higher order organocuprates; palladium-catalyzed coupling with a variety of electrophilic partners affords substituted vinylstannanes.
Preparation
TRANS-1,2-BIS(TRI-N-BUTYLSTANNYL)ETHYLENE is prepared in high yield by the reductive hydrostannation of tributylstannylacetylene with Tri-n-butylstannane and catalytic Azobisisobutyronitrile.
Preparation
TRANS-1,2-BIS(TRI-N-BUTYLSTANNYL)ETHYLENE can be purified by distillation or by preparative reverse-phase chromatography.
