Triphenyl(3,4,5-triiodophenyl)-methane
Reddy, C. Malla,Nangia, Ashwini,Jetti, Ram K. R.,Boese, Roland
, p. o331-o333 (2004)
The crystal structure of the title compound, alternatively called 1,2,3-triiodo-5-(triphenylmethyl)benzene, C25H17I 3, is analysed in terms of I...I and I...π interactions and the herring-bone T motif between phenyl groups. There are two molecules in the asymmetric unit, denoted A and B. Inversion-related A molecules are connected via an I...π interaction (3.641 A, to a C-C bond mid-point) to form an I...π dimer, and these dimers are connected through symmetry-independent B molecules via I...I [3.5571 (15) A] and I...π (3.561 A, to a C-C bond mid-point) interactions.

, p. 2325 - 2334 (2020/05/25)
Using a tripodal, thioether-based ligand comprising a remote protected acetylene, we efficiently stabilize small gold nanoparticles (? ≈ 1.2 nm) which are isolated and purified by chromatography. The 1:1 ligand-to-particle ratio is obtained by comparing t
Divergent Synthesis of Porous Tetraphenylmethane Dendrimers
Urzúa, Julio I.,Torneiro, Mercedes
, p. 13231 - 13238 (2017/12/26)
Tetraphenylmethane-ethynylene-based shape-persistent dendrimers are a new class of nanoobjects with an intriguing 3D architecture. We report an efficient divergent strategy for their synthesis based on the Sonogashira Pd-catalyzed coupling of terminal alkynes with aryl iodides. As repeat unit, we prepared a tetraphenylmethane derivative bearing a terminal alkyne and three triazene moieties. Coupling of this building block to tetrakis(p-iodophenyl)methane afforded, after triazene activation, a dodecaiodo-terminated first generation dendrimer, which was transformed by another Sonogashira coupling into a methoxy-terminated second generation dendrimer with persistent globular shape and well-defined cavities. This work also unveils new aspects of triazene chemistry, i.e., the unprecedented efficient generation of an azo compound by mixing of a triazene with phenol.

Preparation of functionalised tetraphenylmethane derivatives via the Suzuki-Miyaura cross-coupling reaction
Kotha, Sambasivarao,Behera, Manoranjan
, p. 2684 - 2689 (2007/10/03)
A general methodology for the synthesis of various symmetrical and unsymmetrical tetraphenylmethane (TPM) derivatives is reported using the Suzuki-Miyaura (SM) cross-coupling reaction as a key step. The formation of an interesting self-coupling product 14 during the SM cross-coupling reaction of mono-iodo tetraphenylmethane derivative 5 is also observed.
