“…Synthetic access to C [4]s that deviate from classical methylene bridge composition (i.e. those that contain ≥1 different bridge) has been known for some time (32)(33)(34)(35)(36)(37). Elegant work by the Böhmer and Biali groups (amongst others) detailed the synthesis of such species through the use of stepwise and fragment condensation methods.…”

Investigations into cluster formation with alkyl-tethered biscalix[4]arenes Abstract: Calix[4]arenes are versatile ligands capable of forming a wide range of cluster motifs when reacted with 3d, 4f or 3d/4f metal ions. Synthetic modification at the calix[4]arene methylene bridge offers a unique opportunity to explore cluster formation with these alternative building blocks. Here we present the synthesis of a range of bis-calix[4]arenes that are tethered by alkyl chains, as well as exploratory structural studies into cluster-forming reactions. Single crystals were formed in four cases, and from the X-ray structures elucidated it is possible to conclude that sufficiently long alkyl tethers allow for the formation of established cluster topologies without disruption to the core coordination chemistry.

“…Calix[ n ]arene derivatives monobrominated at all bridges ( 2a – 2d ) can be readily prepared by reaction of the corresponding calix[ n ]arene methyl ethers 1a – 1d with NBS under irradiation . The brominated derivatives are useful starting materials for the preparation of methylene‐substituted calixarenes . These compounds readily react with O‐, N‐, S‐ and even some C‐nucleophiles providing a synthetic entry into a wide array of derivatives .…”
