Additions of vinyl- and allyl-titanium bonds to ethylene

Additions of vinyl- and allyl-titanium bonds to ethylene. Lehmkuhl, Herbert; Janssen, Edo; Schwickardi, Renate (Max-Planck-Inst. Kohlenforsch. 3761-92-0 and 7103-09-5 are also occured in this study., Muelheim am der Ruhr D-4330, Fed. Rep. Ger.). J. Organomet. Chem., 258(2), 171-80 (German) 1983. CODEN: JORCAI. ISSN: 0022-328X. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Treating Cp2TiCl (Cp = cyclopentadienyl) with alkylmagnesium halides (alkyl = Me, Et, Pr, CHMe2, hexyl) and ethylene gave Cp2Ti(h3-1-methallyl) (I). Reaction of I with ethylene gave butenes by H transfer and 2,4-hexadienes (II) by addn. of the allyl-Ti bond to ethylene and b-hydride elimination. II were also formed in the catalytic codimerization of butadiene with ethylene in the presence of I, with >99% regioselectivity. .

A Facile Synthesis of 1,1-Bis(silyl)ethenes

A Facile Synthesis of 1,1-Bis(silyl)ethenes. Pawluc, Piotr; Marciniec, Bogdan; Hreczycho, Grzegorz; Gaczewska, Beata; Itami, Yujiro (Department of Organometallic Chemistry, Faculty of Chemistry, Adam Mickiewicz University, Poznan 60-780, Pol.). Journal of Organic Chemistry, 70(1), 370-372 (English) 2005 American Chemical Society.Some commonly used reagents like 7103-09-5 and 130255-49-1 are used in this experiment. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 28 Sym. 1,1-bis(silyl)ethenes were easily prepd. via ruthenium catalyzed silylative coupling-cyclization of 1,2-bis(dimethylvinylsiloxy)ethane. Reaction of chlorodimethylvinylsilane with 1,2-ethanediol gave 1,2-bis(ethenyldimethylsiloxy)ethane (1), which was converted to disilacyclic alkene (2, shown as I) by silylative coupling, catalyzed bu [RuHCl(CO)(PPh3)3]. Hydrolysis of 2 in the presence of HCl gave cyclocarbosiloxane (3, shown as II) with 88% yield. Grignard reaction of 2 with RMgX gave 1,1-disilylethenes (RMe2Si)2C:CH2 (R = Me, Et, Ph, CH:CH2, CH2CH:CH2, CH2CH2CH:CH2). .
