Physical properties
bp 25°C(5 mmHg), d20 = 1.3144 g dm?3.Uses
Methyl Trichlorosilyl Ketene Acetal is widely used as reagent for the enantioselective acetate aldol additions to aldehydes and ketones.Under catalysis by Lewis bases, a variety of aldehydes and ketones react smoothly with Methyl Trichlorosilyl Ketene Acetal at room temperature to afford the aldol addition products in high yields.Preparation
One route is through bis(tributyltin) oxide-catalyzed transmetalation of methyl tributylstannyl acetate (2) with silicon tetrachloride (eq 1).3 When the reaction is complete, excess silicon tetrachloride is removed and the product is purified by fractional distillation under reduced pressure.Check Digit Verification of cas no
The CAS Registry Mumber 4519-10-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4519-10:
(6*4)+(5*5)+(4*1)+(3*9)+(2*1)+(1*0)=82
82 % 10 = 2
So 4519-10-2 is a valid CAS Registry Number.
