Methanolysis of the Cyclic Acetal Function of NanoKid Catalyzed by NanoGoblin, the Pyridinium Salt of Tetracyanocyclopentadienide

Abstract

Small, “doll”-shaped tetracyanocyclopentadienide bearing a 1,3-dioxane acetal “head” and cyano “hands” and “feet” was synthesized. Its pyridinium salt, which was named NanoGoblin, exhibited catalytic activity in the methanolysis of acetals, as demonstrated by the reaction with NanoKid in methanol- d 4 , where the acetal head of NanoKid was converted to a deuterated dimethyl acetal moiety.

Synthetic Routes towards Multifunctional Cyclopentadienes

“…The same group later disclosed the preparation of a rather anthropomorphic TCCP − , coined as NanoGoblin ( 56 ) in honor of the human‐like NanoPutians reported by Tour and Chanteau . On top of its delightful appearance, the NanoGoblin was also found to catalyze the methanolysis of another NanoPutian, the NanoKid (Scheme ) . The sodium salts of TCCP − with a cyano, amino, and nitro group as the fifth substituent were also shown to form polymeric networks upon crystallization, highlighting once more the diverse properties and applications that substituted Cps can show …”

“…[36] On top of its delightful appearance, the NanoGoblin wasa lso found to catalyze the methanolysis of another NanoPutian, the NanoKid (Scheme 10). [37] The sodiums alts of TCCP À with ac yano, amino,a nd nitro group as the fifth substituent were also shown to form polymericn etworks upon crystallization, highlighting once more the diverse properties and applications that substituted Cps can show. [38] The group of Zhenfeng Xi, who was already mentioned for their work with zirconacyclopentadienes, pushed bordersf urther when they reported the first preparation and isolation of novel cyclic dianions, specifically as eries of substitutedo xocyclopentadienyllithium compounds from linear diene-dilithio precursors.…”

Fun with Flags and Chemistry

“…23 Games are an excellent method of active learning in a recreational environment, 24 and many methods have been tested in the past decade: 25 a word game, 26 quiz games, 27−35 card games, 36−38 dice games, 39,40 The link between flags and chemistry has already been attempted by educators, only on the basis of the chemistry necessary to produce the colored dyes. 62 Some authors have tried to connect objects with molecules in order to create a recreative environment, such as structural chemical formulas with human forms (called NanoPutians), 63 monsters (NanGobelin), 64 or racing car shapes. 65,66 The goal of these studies was to educate children in the sciences in an effective and enjoyable manner.…”
