Tris ethylene, pyridination

The vinyldisilane (XXVIII) undergoes chloroplatinic acid-catalyzed hydrosilation with trimethylsilane with great ease at 40° C to give (/J-tri-methylsilylethyl)pentamethyldisilane in 93% yield, which can also be obtained in 80% yield by the addition of pentamethyldisilane to vinyl-trimethylsilane in the presence of tra r-dichloro(ethylene)(pyridine)-platinum(II) as catalyst in benzene at 45° C (128). 

C3-symmetric molecule, benzene-tricarboxamide, has been developed that forms a hydrogel via a similar mechanism [110]. Lee and coworkers synthesized coordination polymers by functionalization of pyridine ligands with dendritic tri(ethylene glycol) chains, which lead to helical chains after the addition of silver ions, forming a 3D network [111],... 

The solvents most commonly employed are water, ethyl and methyl alcohol, ether, benzene, petroleum ether, acetone, glacial acetic acid also two or three solvents may be mixed to get the desired effect as described later. If you still cannot dissolve the compound, try some of these chloroform, carbon disulfide, carbon tetrachloride, ethyl acetate, pyridine, hydrochloric acid, sulfuric acid (acids are usually diluted first), nitrobenzene, aniline, phenol, dioxan, ethylene dichloride, di, tri, tetrachloroethylene, tetrachloroethane, dichloroethyl ether, cyclohexane, cyclohexanol, tetralin, decalin, triacetin, ethylene glycol and its esters and ethers, butyl alcohol, diacetone alcohol, ethyl lactate, isopropyl ether, etc. 

Pyridine may react as a nucleophile with radical cations to pyridinium salts, as in the electrolysis of anthracene in acetonitrile-pyridine which yields a bis-pyridinium-adduct 283 With tris (p-methoxyphenyl)ethylene a tripositive tripyridinium cation is formed (Eq. (124) ) 284 ... 

Neutral ligands that can be used in this reaction include McgCNC, p-MeOCgH4NC, pyridine, PPhg, PEtg, P(OMe)3, and P(OPha) (87, 92). A similar method has been used to prepare the corresponding tri-ethylarsine compounds (88). Reaction of ethylene (1 atm) with PtH(N03)-(PEts)2 gives the cationic complex (XXXII) (129) ...
