There total 10 articles about Bis(cyclopentadienyl)dimethyltitanium 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: 95.0%

bis(cyclopentadienyl)titanium dichloride (1271-19-8) + methyllithium (917-54-4) → dimethyltitanocene (1271-66-5)

Guidance literature:

In diethyl ether; at 0 - 20 ℃; for 0.25h; Inert atmosphere; Schlenk technique;

DOI:10.1021/acs.orglett.9b02572

Reference yield: 85.0%

bis(cyclopentadienyl)titanium dichloride (1271-19-8) + methylmagnesium chloride (676-58-4) → dimethyltitanocene (1271-66-5)

Guidance literature:

In tetrahydrofuran; at -10 - 0 ℃; for 1.33333h; Schlenk technique; Inert atmosphere;

DOI:10.1080/00397911.2013.765484

Reference yield: 84.0%

(C5H5)2TiCH3*(C2H5)2O (74304-33-9) → dimethyltitanocene (1271-66-5) + 2(C5H5)(1-)*Ti(2+)*CS2=(C5H5)2TiCS2

Guidance literature:

With carbon disulfide; In diethyl ether; (Ar); to soln. of Ti complex was added CS2 at -78°C, mixt. was slowly warmed up to room temp. within 2 h and was maintained for 3 at room temp.; soln. was evapd. to dryness and extd. with pentane; yellow crystals were formed upon cooling to -78°C, identified by IR and (1)H-NMR;
