Chemistry is traditionally divided into organic and inorganic chemistry. Application In Synthesis of Titanocenedichloride. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1271-19-8
ADDITION VON VINYL- UND ALLYL-TITAN-BINDUNGEN AN ETHYLEN
Reaction of Cp2TiCl (1) with the alkylmagnesium halides 2a-2d, 2g (alkyl = Me, Et, Pr, iso-Pr, hexyl) and ethylene give bis(eta5-cyclopentadienyl)(eta3-1-methylallyl)titanium (3).Mechanistic investigations indicate that hydrogen transfer from ethylene either to the initially formed Cp2alkytitanium or to Cp2ethyltitanium, formed by betaH-elimination to Cp2titaniumhydride and addition to ethylene, leads to liberation of alkane or alkene and ethane and formation of Cp2vinyltitanium F as an intermediate.Insertion to ethylene (even below 0 deg C) into the vinyl-titanium bond of F leads to Cp23-butenyltitanium, which isomerizes to 3.Reaction of 3 at ca. 80 deg C with ethylene in toluene occurs in part with hydrogen transfer to give the butene isomers 4, 5 and F and in part with addition of the allyl-titanium bond to ethylene to give the 2,4-hexadiene isomers 6a-6c by betaH-elimination.The compounds 6a-6c are also formed in the catalytic codimerization of butadiene with ethylene in the presence of 3.This reaction has a regioselectivity of above 99percent.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Titanocenedichloride, you can also check out more blogs about1271-19-8
