spectra were recorded on a Jeol JNM-AL400 and a Bruker
Avance 300. Proton chemical shifts are reported in ppm (d)
relative to TMS with a solvent resonance employed as internal
standard (residual CHCl3, d 7.26). The data are reported as
follows: chemical shift, multiplicity (s ¼ singlet, d ¼ doublet,
t ¼ triplet, q ¼ quartet, dd ¼ doublet of doublets, dt ¼ doublet of
triplets, m ¼ multiplet), coupling constants (Hz), and integra-
tion. GC-MS analyses were performed with an Agilent 5975C
GC/MS System (Agilent Tech., USA/Germany). FEP tubing
and T-junctions (thru-hole: 0.5 mm, ETFE) were purchased
from Upchurch, USA. Legato 210 (KD Scientific, USA) syringe
pump, PHD 2000 (Harvard Apparatus, USA) syringe pump, and
323S 400 rpm Drive (Watson Marlow, UK) peristaltic pump
were used in the microchemical reactions.

General Description of the Microreactor Mediated Benzylic
Bromination in Concentrated Solar Radiation
A CHCl3 solution of alkylbenzene (0.5 M) was placed in a
syringe, and a CHCl3 solution of Br2 (0.6 M) was placed in
another syringe wrapped with aluminium foil. The reaction
streams were introduced to each of the inlets of the capillary
microreactor through a 25 cm FEP tubing segment. The injec-
tion rates for toluene and Br2 varied but were equal for both
solutions. Sunlight was focussed with a Fresnel lens, and solar
tracking was conducted manually every 15 min. The results of
the reaction were collected into a brown vial containing an
aqueous solution of Na2S2O3. After extraction with additional
CHCl3, the organic layer was analysed. The crude yield and
selectivity were calculated through GC/MS or 1H NMR analy-
sis. The mixtures were purified via column chromatography.
