A series of compounds has been prepared with 4-butylsulfanylphenyl and 4-cyano- or 4-isothiocyanato-phenyl units connected by -CH=CH-, -COO-, -C≡C- , or -C≡C-COO- linking groups. The synthesis of the novel compounds is presented and the transition temperatures and optical parameters of the compounds are discussed and compared with those for related biphenyl reference systems. The ester linking group reduces optical and polarisability anisotropy, but the other linking groups give increased optical anisotropy (up to Δn = 0.50) and polarisability anisotropy [up to Δα = 45.2 A3 (10-30 m3)].

Palladium-catalysed cross-coupling reactions involving haloanilines and arylboronic acids produce the expected biaryl products, but additionally a substantial quantity of the corresponding deaminated biaryl is also generated which constitutes a novel synthetic methodology.
