Various C3-symmetric molecules were prepared by trimerization of acetyl aromatic compounds and subsequently coupled with various boronic acids under Pd0 catalysis conditions to generate oligoaryl/-heteroaryl C3-symmetric molecules. Several furan- and thiophene-containing star-shaped molecules were prepared by the use of Suzuki−Miyauracross-coupling as a key step. Structural and conformational details
Mesoporous Pd‐MCM‐41 catalyzed expeditious synthesis of 1,3,5‐triarylbenzenes and 4‐aryl‐NH‐1,2,3‐triazoles have been developed via denitrative cyclo‐trimerization of β‐nitrostyrenes and de‐nitrative [3+2] cycloaddition of β‐nitrostyrenes with TMSN3 respectively. The catalyst was reused at least up to eight times with minimum loss of catalytic activity.

By performing Friedel–Craftsreaction with a mixture of 1,3,5-tri(furan-2-yl) benzene (TFB) and acetone, we successfully synthesized a cylinder-shaped macrocycle. The isolated yield of 36% is relatively high, considering that twelve C–C bonds are formed simultaneously. The structure of this macrocycle was confirmed using 1H NMR spectroscopy, mass spectrometry and X-ray crystallography. This macrocycle
通过与1,3,5-三(呋喃-2-基)苯(TFB)和丙酮的混合物进行Friedel-Crafts反应,我们成功地合成了圆柱状大环。考虑到同时形成12个C–C键,孤立产率为36%相对较高。该大环的结构使用1 H NMR谱,质谱和X射线晶体学确认。这个大环能够识别由阳离子-偶极子和CH-π相互作用驱动的各种阳离子客体。

A prism-shaped cage was obtained via the Friedel–Craftsreaction in a 2:3 mixture of trisfuryl and bis-isopropenyl precursors, in a remarkable yield of 40% considering six C–C bonds formed in a one-pot manner. The cage contains two π-electron rich trisfuryl platforms bridged in a face-to-face manner with three p-xylylene linkers. Therefore, it enables accommodation of π-electron poor guests with complementary
