Reaction of Zn(C6F5)2·toluene (two equivalents) with 1,3-dipropoxy-p-tert-butyl-calix[4]arene (L(1)H2) led to the isolation of the complex [{Zn(C6F5)}2L(1)] (1), whilst similar use of Zn(Me)2 resulted in the known complex [{Zn(Me)}2L(1)] (2). Treatment of L(1)H2 with in situ prepared Zn{N(SiMe3)2}2 in refluxing toluene led to the isolation of the compound [(Na)ZnN(SiMe3)2L(1)] (3). The stepwise...

Reactions of 0.5 eq. of the dinuclear complexes [(g-arene)Ru(l-Cl)Cl]2 (arene = g-C6H6, g-p-PrC6H4Me) and [(Cp*)M(l-Cl)Cl]2 (M = Rh, Ir; Cp* = g-C5Me5) with 4,6-disubstituted pyrazolyl-pyrimidine ligands (L) viz. 4,6-bis(pyrazolyl)pyrimidine (L1), 4,6-bis(3-methyl-pyrazolyl)pyrimidine (L2), 4,6-bis(3,5dimethyl-pyrazolyl)pyrimidine (L3) lead to the formation of the cationic mononuclear complexes...

A pillar[4]arene[1]quinone and a difunctionalized pillar[5]arene have been synthesized by partial oxidation.

A macro-/mesoporous polymeric network with densely incorporated pillar[5]arene functionality was prepared via ionic complexation between a polymerized ionic liquid and carboxylated pillar[5]arene. It retained the solution-state host-guest property of the pillar[5]arene and was successfully applied as a selective absorbent for n-alklyene diols.

Cofacial Fe2, Co2, and Ni2 complexes supported by a para-terphenyl diphosphine ligand were prepared. Central arene deplanarization and a μ2:(η(3),η(3)) coordination mode suggest partial bisallyl character in the Fe2 and Co2 complexes. An oxidation induced shift in Fe2-arene binding highlights the non-innocent nature of the arene ligand.

The low density polymorph of the well-known host p-tert-butylcalix[4]arene absorbs more methane than p-tert-pentylcalix[4]arene at room temperature and 1 atm pressure, but the order of absorption is reversed at 38 atm with p-tert-pentylcalix[4]arene absorbing more.

Arene oxide derivatives of carcinogenic polycyclic hydro carbons have been postulated as the reactive intermediates responsible for the in vivo binding of the parent hydrocar bon to cellular nucleic acids. In this study the reaction of 12 different Kand non-K-region arene oxides and 7 benzo(a)pyrene phenols with polyguanylic acid in aqueous acetone solutions has been investigated. The extent of...

For the surface-optoelectronic study of Saxitoxin sensing, we fabricated selfassembled calix[4]arene derivative monolayers as the recognition-functional interfaces on a gold surface. An interaction study between Saxitoxin and calix[4]arene derivative monolayers were performed using surface plasmon resonance (SPR) spectroscopy. Among three calix[4]arene derivatives, calix[4]arene crown ether SAM...

In the title compound, C(6)BrF(4)NO(2), the nitro group is twisted by 41.7 (3)° with reference to the arene ring mean plane. The main inter-actions stabilizing the crystal structure include O⋯Br contacts [3.150 (2) and 3.201 (2) Å], while F⋯F inter-actions are minor [2.863 (3)-2.908 (3) Å].
