Technology Process of Ti(η4-C4Ph4)(COT)

There total 6 articles about Ti(η4-C4Ph4)(COT) which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 60.0%

Ti(η4-tetraphenylcyclobutadiene){(μ-Br)2(AlBr2)}2 (113809-75-9) + dipotassium cyclooctatetraenide (34480-05-2) → Ti(η4-C4Ph4)(COT) (39475-28-0)

Guidance literature:

In toluene; addn of Ti-complex to stirred suspn. of K2COT, 6h stirring, room temp., filtered, concd., pptn. by addn. of n-heptane, filtration, dried in vac. at room temp.; elem. anal., detected by IR;

Reference yield: 40.0%

[(C8H8)Ti(C6H5)C2(C6H5)]2 → C8H8TiC4(C6H5)4 (39475-28-0)

Guidance literature:

In neat (no solvent); byproducts: trans-stilbene; Ti-complex was heated under N2 at 180°C for 5 h; extd. with toluene, concd., pentane was added, cooled, extd. with hexane; elem. anal.;

Reference yield: 15.0%

{(η8-cyclooctatetraenyl)(μ-Cl)titanium(III)(THF)}2 + diphenyl acetylene (501-65-5) → Ti(η4-C4Ph4)(COT) (39475-28-0)

Guidance literature:

With Mg; In tetrahydrofuran; byproducts: MgCl2, hexaphenylbenzene; absence of air and moisture; heating Ti-complex with excess of Ph2C2 and Mg turnings (60°C, 8 h); decantation, repeated evapn. (vac.) and extn. into hexane;
