Amides chloride

A solution of the amide chloride (4.6 g) in dry, alcohol-free chloroform (20 ml) was added slowly to a solution of trimethylsilyl 6-amino-penicillanate (7.2 g) and triethylamine (3.5 ml) in dry, alcohol-free chloroform (50 ml) with stirring and cooling to -70°C. The temperature was raised to 0°C during 1V4 hours. The solution was evaporated to dryness in vacua and the residue was triturated with dry ether (200 ml). The precipitate was filtered off and washed with dry ether. The filtrate was diluted with ether (200 ml). 2-Butanol (2.8 ml) was added dropwise with stirring and cooling to0°C. The stirring was continued for A hour at 0°C, whereupon the precipitate was filtered off, washed with ether and dried. It was a white, amorphous powder, soluble in water. [Pg.905]

Several min after addition of ethanol to a mixture of the amide chloride ( fusible white precipitate ) and iodine, an explosion occurs. Addition of the compound to chlorine gas or bromine vapour leads to a delayed violent or explosive reaction. Amminemetal salts behave similarly, and formation of A-halogen compounds is involved in all cases. [Pg.1364]

The reaction between amides and PC15, which leads by way of the amide chlorides to the imide chlorides, need merely be mentioned here. [Pg.131]

Chlormethanphosphomaurc- [(chlor-diethylamino-methylen)-amid]-chlorid erhalt man in 73%iger Ausbeute nach 24stiindigem Erhitzen auf 100-120° von 1 Mol Diethylcyanamid und 1,5 Mol Chlormethanphosphonsaure-dichlorid nach Abdestillieren von iiberschiissi-gem Phosphonsaure-dichlorid. [Pg.341]

Phosphonsaure-amid-chloride reagieren mit Aminen zu Phosphonsaure-diamiden. Bei sterischer Behinderung miissen Temperaturen von 100° und hochkonzentrierte Losun-gen verwendet werden. So erhalt man aus 1-Methyl-ethanphosphonsaure-chlorid-dime-thylamid mit Diethylamin ohne Losungsmittel erst nach lstdg. Erhitzen auf 100° 7-Methyl-ethanphosphonsdure-diethylamid-dimethylamid (Sdp. 83—85°/0,15 Torr (20 Pa)642. [Pg.417]

Phosphonigsaure-amid-chloride lassen sich mit elementarem Schwefel in siedendem Benzol in 70-95% zu Thiophosphonsaure-amid-chloriden sulfurieren748. Die Reaktion ver-lauft ohne Anwesenheit von Katalysatoren. Dimethylamino-fluor-trifluormethyl-phos-phan geht mit Schwefel ohne Katalysatoren allerdings erst bei 180° in 6 Tagen in Trifluor-methan-thiophosphonsdure-dimethylamid-fluorid iiber749. [Pg.435]
