PHOTOSILYLATION OF ELECTRON-DEFICIENT ALKENES BY USE OF DISILANES VIA PHOTOINDUCED ELECTRON-TRANSFER
The photosilylation on electron-deficient alkenes such as 1-aryl-2,2-dicyanoethenes occurred regioselectively at the β-position to the electron-withdrawing groups upon irradiation with disilanes and trisilane.
Photochemical carbon-silicon bond forming reaction on electron-deficient alkenes by disilanes and polysilanes via photoinduced electron transfer
The phenanthrene-sensitized photoreaction of electron-deficient alkenes with disilanes in acetonitrile gave silylated alkanes in high yields.The photosilylation occurred in a highly regioselective manner at the position β to the electron-withdrawing group
