Phosgene and tertiary carboxylic acid amides form very labile adducts (17 equation 6 not yet isolated or used for preparative purposes as such), which decompose with loss of CO2 very rapidly to give amide chlorides (see Section 2.7.2.2.1.i). Decomposition with evolution of CO2 is a common fate of primary adducts of carbonic acid chloride derivatives. Primary adducts from DMF and chloroformic acid esters (18), for example, decompose immediately to give alkoxymethyleneiminium chlorides, which react to give alkyl chlorides and DMF (equation 7). Adducts (19) from secondary and tertiary carboxamides... [Pg.491]

Not only the Pinner synthesis provides alkoxymethyleneiminium salts the action of chloroformic acid esters on primary or secondary amides or thioamides ° as well as on lactams is a versatile method to get these salts and from them the imino esters, e.g. (230 equation 125). Primary and secondary amides have been alkylated by several reagents and the iminium salts thus formed were converted to imino esters with the aid of bases. A collection of imino esters prepared by this method can be found in a review the more recent results listed in Table 5 demonstrate the scope of this procedure. [Pg.529]

In the manufacture of benzylchloroformate, liquid phosgene and cold toluene were charged to a glass-lined reactor. These components were followed by the slow addition of benzyl alcohol. After completion of the reaction, toluene was distilled off under vacuum. On one occasion, a violent explosion occurred towards the end of the distillation process. The investigation revealed that the cause of the explosion was the catalytic decomposition of the chloroformic acid ester produced, by iron ions present in the liquid phosgene. [Pg.163]
