present the use of the tert-butyldimethylsilyl amine (TBDMS-NH2) as a silylating reagent for phenols, benzylalcohols, and carboxylic acids. Unlike other silyl protection reactions, this reported process with TBDMS-NH2 does not involve the formation of HCl. Importantly, we report the efficacy of this reagent in operating undersolvent-freeconditions and enabling short reaction times.

Biary ethers are known to be important organic compounds for their biological interests and great presence in life science industries. A number of them have consequently provide a strong incentive for synthesis, which includes the classical Ullman reaction, metal-catalyzed substitution, SN-Ar based type, intramolecular oxidative coupling and MW-assisted methods. Although the above synthetic strategies
We report metallo-supramolecular interlocked hexagonal self-assembly associated with the near-IR detection of Pb2+ ions and thiols in water using a perylene diimide probe.
