(E)-Propenyltriethoxysilane, also known as (E)-3-triethoxysilyl-1-propene, is an organosilicon compound with the chemical formula C?H??OSi. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 146.26 g/mol. (E)-propenyltriethoxysilane is primarily used as a coupling agent in the production of composite materials, particularly in the reinforcement of plastics and rubber with fillers such as glass fibers, calcium carbonate, and silica. It functions by forming covalent bonds between the inorganic fillers and the organic polymer matrix, enhancing the mechanical properties and durability of the final product. (E)-Propenyltriethoxysilane is also employed as a crosslinking agent in the synthesis of silicone resins and as a silylating agent in organic synthesis. Due to its reactivity with moisture, it is typically handled under anhydrous conditions and is considered a hazardous material with potential health and environmental risks.

Check Digit Verification of cas no

The CAS Registry Mumber 2550-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2550-03:
(6*2)+(5*5)+(4*5)+(3*0)+(2*0)+(1*3)=60
60 % 10 = 0
So 2550-03-0 is a valid CAS Registry Number.

Isomerization of allyltrisubstituted silanes and decenes accompanying their cometathesis in the presence of ruthenium complexes

Foltynowicz,Krompiec,Wagner,Maciejewski

, p. 468 - 475 (2007/10/03)

It was found that the product of cometathesis of allyltrisubstituted silanes and 1-decene in the presence of different complexes of ruthenium was (E)-and (Z)-R3SiCH=CHR1 (R = Me or EtO; R1 = n-C8H17.). The cometathesis was accompanied by the migration of a double bond in allylsilanes and 1-decene. The isomerization of allyltrisubstituted silanes to appropriate propenyltrisubstituted silanes as well as of 1-, 2-, and 4 - alkenes to isomeric alkenes in the presence of ruthenium complexes was investigated too. It was proved that the migration of a double bond is accompanied by (E) - (Z) isomerization. Products of the first stage of the migration reaction are mainly (E) isomers. Isomerization proceeds at lower temperatures than cometathesis. Tetrachloroethylene as a solvent was favorable for isomerization, but it inhibited cometathesis.
