Studies on the Reactivity of Antimony Pentachloride. III. The Reaction of Antimony(V) Chloride and MethylisocyanateMethylisocyanate CH3NCO reacts with SbCl5 in boiling CCl4 by an insertion-reaction to a product of the formula C5H6Cl9N2O2Sb I, which has the chlorformamidinium-structure (Cl—C(O)—N(CH3)—CCl—N(CH3)—C(O)—Cl)⊕SbCl6⊖. Hydrolysis of I yields the heterocycle C5H6N2O4 II. The reaction with methanol gives (CH3—NH—CCl—NH—CH3)⊕SbCl6⊖ III and (CH3—NH—CCl—N(CH3)—C(O)—OCH3)⊕SbCl6⊖ IV. The i.r. and Raman spectra of the compounds I, III and IV are discussed.
Notes:
Methylisocyanat CH3NCO reagiert in der Siedehitze mit Antimonpentachlorid SbCl5 und Tetrachlorkohlenstoff CCl4 in einer Einschiebungs-Reaktion zu einem Produkt der Summenformel C5H6Cl9N2O2Sb I mit Chlorformamidinium-Struktur (Cl—C(O)—N(CH3)—CCl—N(CH3)—C(O)—Cl)⊕SbCl6⊖. Bei der Hydrolyse von I entsteht der Heterocyclus C5H6N2O4 II. Die Alkoholyse mit Methanol ergibt (CH3—NH—CCl—NH—CH3)⊕SbCl6⊖ III und (CH3—NH—CCl—N(CH3)—C(O)—OCH3)⊕SbCl6 IV. Eine Zuordnung der IR- und Raman-Spektren von I, III und IV wird vorgeschlagen.
