Calculate Digit Verification of CAS Registry Number 67734-38:
(7*6)+(6*7)+(5*7)+(4*3)+(3*4)+(2*3)+(1*8)=157
157 % 10 = 7

Preparation of unsaturated ketones

-

, (2008/06/13)

Unsaturated ketones of the formulae Ia and Ib are prepared by a process consisting of the combination of the following reactions:a) The conventional reaction of an allyl alcohol of the formula IIa or a propargyl alcohol of the formula IIb with an isopropenyl ether of the formula III with formation of a ketal of the formula IV as a byproduct,b) preparation of the isopropenyl ether of the formula III by reacting a ketal of the formula IV with propyne or allene, or a mixture thereof in the gas phase at elevated temperatures in the presence of a heterogeneous catalyst containing zinc or cadmium together with silicon or oxygen, andc) feeding the ketal of the formula IV formed in the reaction (a) into stage (b) for the preparation of the isopropenyl ether of the formula III again.
