60212-31-9 Usage
General Description
4-Undecyne, also known as undec-4-yne, is a chemical compound with the molecular formula C11H20. It is a terminal alkyne, meaning that it contains a triple bond at the end of the carbon chain. 4-Undecyne is a colorless liquid with a characteristic odor, and it is insoluble in water but soluble in organic solvents. It is commonly used in organic synthesis and as a starting material for the production of various chemicals and pharmaceuticals. Additionally, it has applications in the field of nanotechnology and materials science, where it is used to functionalize surfaces and create new materials with specific properties. 4-Undecyne is also used as a reagent in the production of polymers and in the formulation of coatings and adhesives. However, it is important to handle 4-Undecyne with care, as it is flammable and may cause skin and respiratory irritation upon exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 60212-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,2,1 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 60212-31:
(7*6)+(6*0)+(5*2)+(4*1)+(3*2)+(2*3)+(1*1)=69
69 % 10 = 9
So 60212-31-9 is a valid CAS Registry Number.

Applications of phase-transfer catalysis. lxv alkylation of alkynes under phase transfer catalysis
Dehmlow, Eckehard Volker,Fastabend, Uwe

Phenylacetyle ne can be propylated by propyl bromide in toluene at 80-110 °C in the presence of excess powdered potassium hydroxide and 2 mol % of 18-crown-6. Aliphatic alkynes are deprotonated effectively only by NaNH2, NaH, or KH. Whereas this step proceeds without catalyst, subsequent alkylation needs the presence of a PT catalyst at 80 °C in toluene. The most useful catalyst for this conversion is Schwesinger's salt, whase lipophilic cation seems to solubilize the acetylide anion.
