118336-86-0 Usage
Uses
2-(4-Chlorobutyl)-1,3-dioxolane was used in the synthesis of C-chlorobutylpyrogallol[4]arene.
Purification Methods
If the IR has no CHO band, then just distil it in a vacuum. If it is present, then dissolve it in Et2O, wash it with H2O, then saturated NaHCO3, dry over MgSO4, evaporate and distil it. [cf Kriesat & Gisvold J Pharm Sci 60 1250 1971, Loftfield J Am Chem Soc 73 1365 1951.]
Check Digit Verification of cas no
The CAS Registry Mumber 118336-86-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,3 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118336-86:
(8*1)+(7*1)+(6*8)+(5*3)+(4*3)+(3*6)+(2*8)+(1*6)=130
130 % 10 = 0
So 118336-86-0 is a valid CAS Registry Number.

Dienediolates of unsaturated carboxylic acids in synthesis. Aldehydes and ketones from alkyl halides, by ozonolysis of β,γ-unsaturated α-alkyl carboxylic acids. The role of a tertiary amine in the cleavage of ozonides

A convenient two-step procedure for a two carbon homologative conversion of alkyl halides into aldehydes and methyl ketones by α-alkylation of unsaturated carboxylic acids, followed by ozonolysis is developed and applied to the synthesis of ω-chloro aldehydes. Triethylamine is superior to dimethyl sulfide or triphenylphosphine for cleavage of the ozonides, except when aldol condensation side reactions require use of protic solvents and iodide salts. Cleavage of the ozonides by triethylamine is shown to occur mainly through a reductive process.
