1-(Ethenyloxy)propadiene, also known as 1-(allyloxy)buta-1,3-diene, is an organic compound with the chemical formula C6H8O. It is a colorless liquid that is insoluble in water but soluble in organic solvents. This molecule features a propadiene backbone with an allyl ether group attached to the terminal carbon. It is synthesized by the reaction of allyl alcohol with propadiene and is used as an intermediate in the production of various organic compounds, such as pharmaceuticals and agrochemicals. Due to its reactive nature, it is sensitive to heat and light, and should be stored under cool, dry conditions.

4409-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4409-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4409-99:
(6*4)+(5*4)+(4*0)+(3*9)+(2*9)+(1*9)=98
98 % 10 = 8
So 4409-99-8 is a valid CAS Registry Number.

HYDRATION TRIMERIZATION OF ACETYLENE IN SUPERBASIC MEDIA. IV. VINYLOXYALKYNES, VINYLOXYALLENES, AND VINYLOXY-1,3-DIENES FROM ALDEHYDES AND ACETYLENE IN A SINGLE PREPARATIVE STAGE.

Tarasova, O. A.,Trofimov, B. A.,Keiko, V. V.,Amosova, S. V.

, p. 1026 - 1028 (2007/10/02)

The reaction of aliphatic aldehydes with acetylene in the potassium hydroxide-DMSO system was investigated.As a result of the reaction at 55-65 deg C 3-vinyloxy-1-alkynes and 3-vinyloxy-1,2-alkadienes were obtained with an overall yield of 12-69percent.Fr

HYDRATION TRIMERIZATION OF ACETYLENE IN SUPERBASIC MEDIA III. VINYLATION OF ACETYLENIC ALCOHOLS AS INTERMEDIATE STAGE

Tarasova, O. A.,Trofimov, B. A.,Afonin, A. V.,Sinegovskaya, L. M.,Kalinina, N. A.,Amosova, S. V.

, p. 1018 - 1025 (2007/10/02)

It was confirmed that the hydration-trimerization of acetylene to 2-vinyloxy-1,3-butadiene in superbasic media takes place by a stepwise mechanism, involving the initial formation of acetaldehyde, its ethynylation, vinylation of the acetylenic alcohol, and prototropic acetyl-allene-1,3-diene rearrangements.A method was developed for the direct vinylation of primary and secondary acetylenic alcohols in the potassium hydroxide-DMSO system, leading to 3-vinyloxy-1-alkynes and 3-vinyloxy-1,2-alkadienes with overall yields of 45-87percent .
