119690-91-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119690-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,9 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119690-91:
(8*1)+(7*1)+(6*9)+(5*6)+(4*9)+(3*0)+(2*9)+(1*1)=154
154 % 10 = 4
So 119690-91-4 is a valid CAS Registry Number.

Iridium-Catalyzed Distal Hydroboration of Aliphatic Internal Alkenes

Wang, Guangzhu,Liang, Xinyi,Chen, Lili,Gao, Qian,Wang, Jian-Guo,Zhang, Panke,Peng, Qian,Xu, Senmiao

, p. 8187 - 8191 (2019)

The regioselective hydroboration of aliphatic internal alkenes remains a great challenge. Reported herein is an iridium-catalyzed hydroboration of aliphatic internal alkenes, providing distal-borylated products in good to excellent yields with high regioselectivity (up to 99:1). We also demonstrate that the C?B bond of the distal-borylated product can be readily converted into other functional groups. DFT calculations indicate that the reaction proceeds through an unexpected IrIII/IrV cycle.

REACTION OF OXIRANES WITH DIANIONS OF SECONDARY AMINES. NEW ENTRY TO 5-ALKYLSUBSTITUTED γ-LACTAMS

Takahata, Hiroki,Wang, Eng-Chi,Yamazaki, Takao

, p. 1159 - 1166 (2007/10/02)

The oxirane ring cleavage with dilithiated secondary amides was accelerated by the addition of boron trifluoride-etherate to afford γ-hydroxyamides, which were transformed into 5-alkylsubstituted γ-lactams via an intramolecular N-alkylation reaction.
