Cross Coupling Reactions

Hydrozirconation of terminal alkynes 1 gives (E)-alkenylzirconium complexes 3, which cross-couple with (E)-α-iodovinyltellurides 4 in the presence of [Pd(PPh3)4] catalyst to afford stereoselectively 1,3-dienyltellurides 5 in good yields.

New Entry

A regio- and stereoselective synthesis of (Z)-β-halo alkenyl sulfides via K2CO3-promoted hydrothiolation of haloalkynes has been reported, permitting a new entry to trisubstituted alkenes featuring the iterative cross-coupling of carbon–halide and carbon–sulfur bonds.
