199920-91-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 199920-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 199920-91:
(8*1)+(7*9)+(6*9)+(5*9)+(4*2)+(3*0)+(2*9)+(1*1)=197
197 % 10 = 7
So 199920-91-7 is a valid CAS Registry Number.

Transmetalation of Alkylboranes to Palladium in the Suzuki Coupling Reaction Proceeds with Retention of Stereochemistry

Ridgway, Brian H.,Woerpel

, p. 458 - 460 (1998)

Deuterium-labeling experiments demonstrate that the transmetalation step of the Suzuki coupling reaction of alkylboranes and α-iodoenones proceeds with retention of stereochemistry.

A Cooperative Strategy for the Highly Selective Intermolecular Oxycarbonylation Reaction of Alkenes using a Palladium Catalyst

Li, Ming,Yu, Feng,Qi, Xiaoxu,Chen, Pinhong,Liu, Guosheng

supporting information, p. 13843 - 13848 (2016/10/26)

A novel method for intermolecular functionalization of terminal and internal alkenes has been designed. The electrophilic reagent, hypervalent iodine, plays a key role in this process by activating the alkene C=C bond for nucleophilic addition of the palladium catalyst. This process generates an iodonium-containing palladium species which undergoes CO insertion. The new approach, intermolecular oxycarbonylaton reactions of alkenes, has been achieved and carried out under mild reaction conditions to produce the corresponding β-oxycarbonylic acids with excellent efficiencies and levels of regio- and diastereoselectivity.
