Time-dependent stereoselective Heck reaction using mesoporous Pd/TiO2 nanoparticles catalyst under sunlightElectronic supplementary information (ESI) available: SEM, TEM, EDS and FTIR data of Pd/TiO2 catalyst is shown. The characterization of coupling products by GC-MS and 1H and 13C NMR spectra is shown. See DOI: 10.1039/c3cy00602f

| Summary: | Pd(0)-doped mesoporous TiO
2
nanoparticles (Pd/TiO
2
) have been synthesized using an EISA method. The catalytic activity of Pd/TiO
2
nanoparticles (NPs) is significantly enhanced under solar light irradiation for the Heck reaction. The Heck coupling product gives a considerable amount of
Z
-isomer, due to photochemical isomerization of the initially formed
E
-isomer, providing a facility for the time-dependent selectivity of
E
/
Z
-isomers under sunlight at ambient conditions.
Pd-doped mesoporous TiO
2
nanoparticles (Pd/TiO
2
) have been synthesized and used as a photocatalyst for Heck reactions giving time-dependent selectivity of
E
-/
Z
-isomer formation in good yields. |
