329-13-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 329-13-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 329-13:
(5*3)+(4*2)+(3*9)+(2*1)+(1*3)=55
55 % 10 = 5
So 329-13-5 is a valid CAS Registry Number.

PROCESSES FOR FLUORINATION

-

Paragraph 0179; 0184; 0214-0215; 0222, (2021/04/10)

The present technology relates to fluorination reactions. Specifically, processes useful for making the fungicide compound, DFT are disclosed. More broadly, also disclosed herein are processes useful for deoxyfluorination at the α-aromatic position of a given compound.

We report a redox-neutral method for nucleophilic fluorination of N-hydroxyphthalimide esters using an Ir photocatalyst under visible light irradiation. The method provides access to a broad range of aliphatic fluorides, including primary, secondary, and tertiary benzylic fluorides as well as unactivated tertiary fluorides, that are typically inaccessible by nucleophilic fluorination due to competing elimination. In addition, we show that the decarboxylative fluorination conditions are readily adapted to radiofluorination with [18F]KF. We propose that the reactions proceed by two electron transfers between the Ir catalyst and redox-active ester substrate to afford a carbocation intermediate that undergoes subsequent trapping by fluoride. Examples of trapping with O- and C-centered nucleophiles and deoxyfluorination via N-hydroxyphthalimidoyl oxalates are also presented, suggesting that this approach may offer a general blueprint for affecting redox-neutral SN1 substitutions under mild conditions.
