20700-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20700-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,0 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20700-46:
(7*2)+(6*0)+(5*7)+(4*0)+(3*0)+(2*4)+(1*6)=63
63 % 10 = 3
So 20700-46-3 is a valid CAS Registry Number.

Copper-Catalyzed Direct Coupling of Unprotected Propargylic Alcohols with P(O)H Compounds: Access to Allenylphosphoryl Compounds under Ligand- and Base-Free Conditions

Hu, Gaobo,Shan, Changkai,Chen, Weizhu,Xu, Pengxiang,Gao, Yuxing,Zhao, Yufen

supporting information, p. 6066 - 6069 (2016/12/09)

The first facile and efficient copper-catalyzed direct C-P cross-coupling of unprotected propargylic alcohols with P(O)H compounds has been developed, providing a general, one-step approach to construct valuable allenylphosphoryl frameworks with operational simplicity and high step- and atom-economy under ligand-, base-, and additive-free conditions.

Convenient synthesis of allenylphosphoryl compounds: Via Cu-catalysed couplings of P(O)H compounds with propargyl acetates

Shen, Ruwei,Luo, Bing,Yang, Jianlin,Zhang, Lixiong,Han, Li-Biao

supporting information, p. 6451 - 6454 (2016/05/24)

A novel Cu-catalysed substitution reaction of propargyl acetates with P(O)H compounds is developed to afford allenylphosphoryl compounds via C-P bond coupling in high yields under mild conditions. A plausible mechanism involving the nucleophilic interception of the Cu-allenylidene intermediates is proposed.
