A route towards phenylene-bithiophene macrocycles via oxidativethiophene coupling under pseudo-high dilution conditions is reported. This method is applied to the synthesis of a shape-persistent thiophenemacrocycle with extraannularly attached perylenebisimide moieties that forms supramolecular aggregates at the solid/liquid interface.
Regioselective functionalization of arenes remains a challenging problem in organic synthesis. Steric interactions are often used to block sites adjacent to a given substituent, but they do not distinguish the remaining remote sites. We report a strategy based on remote steric control, whereby a roof-like ligand protects the distant para site in addition to the ortho sites, and thereby enables selective

A method of creating a tubular compound includes providing an end cap including a macrocycle that is sufficiently rigid that it presents a plurality of functional groups oriented axially on or extending axially from a first axial side of the end cap, creating a tubular wall from a plurality of reactive compounds which is covalently attached to the end cap via reaction of the plurality of functional groups extending from the first axial side of the end cap, the tubular wall extending axially from the first axial side end cap, and performing at least one equatorial cyclization reaction axially distant from the end cap which includes covalent bonding of residues of a group of the plurality of reactive compounds used in forming the tubular wall.

efficient access to aryl boronic esters. Using in situ catalyst activation and photoirradiation, the iron-catalysed C(sp2)-H borylation reaction of carboarenes, pyrroles, and indoles has been developed using only bench-stable pre-catalysts and reagents. Good functional group tolerance was observed including those not reported using previous methods (ArNH2, ArOH, ArSiR3, ArP(O)(OR)2, ArC(O)NR2). Mechanistic
