The retinal analogues ( 13Z)-13-bromo-13-desmethylretinal (3) and ( 13E)-20,20,20-trifluororetinal (4) have been efficiently synthesized using the palladium-catalyzed cross-coupling of boronic acid 8 and electrophiles 9 and 10, respectively. For the first analogue, the coupling of 8 and the gem-dibr
