The synthesis and transition temperatures are reported for several 2-(4-alkyl- and 4-alkoxy-phenyl)-5-cyano-1-benzofurans, 2-(4'-alkylbiphenyl-4-yl)-5-cyano- and 5-(4'-alkylbiphenyl-4-yl)-2-cyano-1-benzofurans, and for compounds with other combinations of terminal alkyl and cyano groups in 2,5-disubstituted-1-benzofurans containing two phenyl units; some isolated examples of related cyclohexane systems are also presented. The mesogenic behaviour of these compounds and several intermediates (e.g. amides, acids and esters) is discussed and the transition temperatures are rationalised on the following basis (a) 1-benzofuran is a superior core unit to benzene, (b) 2,5-disubstitution in 1-benzofuran gives a bent core which adversely affects mesogenicity, to an extent which depends on its position in the core, (c) antiparallel associations in terminal cyano compounds can eliminate the disadvantage of a bent core structure, (d) 2-aryl-1-benzofurans have negligible inter-annular twist but 5-aryl-1-benzofurans have similar inter-annular twist to that in biphenyls.

The generation of metal carbenoids viaringopening of cyclopropenes by transition metals offers a simple entry into highly reactive intermediates. Herein, we describe a diastereoselective intermolecular rhodium-catalyzed cyclopropanation of heterocycles and alkenes using cyclopropenes as carbene precursors with a low loading of a commercially available rhodium catalyst. The reported method is scalable
