Description
Lanthanum isopropoxide is a chemical compound with the formula La(OiPr)3, where La represents the element Lanthanum and OiPr stands for isopropoxide (-OCH(CH3)2). It is an off-white to pale yellow powder and is known for its application in various chemical processes, particularly in asymmetric catalysis.
Uses
1. Used in Asymmetric Catalysis:
Lanthanum isopropoxide is used as a catalyst in asymmetric catalysis for enhancing the 1,4-addition of malonate to cyclic and acyclic enones. This application is due to its ability to form a complex with an (S,S)-phenyl-linked-binaphthol, which improves the efficiency and selectivity of the reaction.
2. Used as a Co-catalyst in Catalytic Allylation of Ketoimines:
In the chemical industry, Lanthanum isopropoxide is also utilized as a co-catalyst alongside copper fluoride-triphenylphosphine in the general catalytic allylation of ketoimines. This use is attributed to its ability to facilitate the reaction and improve the overall yield of the desired product.
Check Digit Verification of cas no
The CAS Registry Mumber 19446-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19446-52:
(7*1)+(6*9)+(5*4)+(4*4)+(3*6)+(2*5)+(1*2)=127
127 % 10 = 7
So 19446-52-7 is a valid CAS Registry Number.
