850568-54-6 Usage

Uses

Benzene boronic acid mediated the ortho specific hydroxyalkylation of phenols by aldehydes. The ability of boronic acids to reversibly bind diol functional groups has been utilized for fluorescent detection of saccharides. It can be a effective catalyst for amidation and esterification of carboxylic acids.

Check Digit Verification of cas no

The CAS Registry Mumber 850568-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,5,6 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 850568-54:
(8*8)+(7*5)+(6*0)+(5*5)+(4*6)+(3*8)+(2*5)+(1*4)=186
186 % 10 = 6
So 850568-54-6 is a valid CAS Registry Number.

A New Approach to Non-Coordinating Anions: Lewis Acid Enhancement of Porphyrin Metal Centers in a Zwitterionic Metal-Organic Framework

Johnson, Jacob A.,Petersen, Brenna M.,Kormos, Attila,Echeverría, Elena,Chen, Yu-Sheng,Zhang, Jian

supporting information, p. 10293 - 10298 (2016/09/03)

We describe a new strategy to generate non-coordinating anions using zwitterionic metal-organic frameworks (MOFs). By assembly of anionic inorganic secondary building blocks (SBUs) ([In(CO2)4]-) with cationic metalloporphyrin-based organic linkers, we prepared zwitterionic MOFs in which the complete internal charge separation effectively prevents the potential binding of the counteranion to the cationic metal center. We demonstrate the enhanced Lewis acidity of MnIII- and FeIII-porphyrins in the zwitterionic MOFs in three representative electrocyclization reactions: [2 + 1] cycloisomerization of enynes, [3 + 2] cycloaddition of aziridines and alkenes, and [4 + 2] hetero-Diels-Alder cycloaddition of aldehydes with dienes. This work paves a new way to design functional MOFs for tunable chemical catalysis.
