Abstract
The reaction of TiCl4 with different isocyanides did not lead to any insertion of the isocyanide functionality into the Ti-Cl bond but to simple adducts such as {[TiCl3(2,6-Me2C6H3NC)]2(mu-2-Cl)2}, [(TiCl4)2(mu-2-O = P(OEt2CH2NC)2], and [(TiCl4)2(mu-2-O = C(OEt)CH2NC)2]. This ruled out any organometallic pathway in the Passerini reaction assisted by TiCl4. The present mechanism is proposed on the basis of the isolation and structural characterization of the key intermediateFile in questo prodotto:
