5 grams of isobutylamine being mixed with 7 grams of alljl for- 

 mate the temperature rose to 75°. The — not as yet described — 

 isobutylformamide boiled at 229"". 



5 grams of allylamine being mixed with 10 grams of the ester the 

 temperature rose to 65° and the allyl alcohol being removed by 

 distillation, allylforraamide was obtained (b.p. 220°. 5). 



With benzylamine (5 grams) and allyl formate (5 grams) the 

 temperature rose from 19° to 55°. The alcohol being distilled off 

 and allowed to cool to the ordinary temperature, there remained 

 in the flask a solid mass, m. p. 62". The melthig point was not 

 altered after recrystallisation the compound from petroleum ether, 

 which is very suitable for this purpose. 



Benzylformamide was first obtained by Holleman ^), who described 

 it as a substance melting at 49\ This statement is probably due to a 

 clerical error, at least, a specimen prepared by Prof. Hoi.leman and 

 kindly presented to me by Dr. Yermeui-ex of the Groningen Labora- 

 tory did not begin to soften until 59°. Boiling petroleum ether 

 extracted a substance melting at 62°, which on being mixed with 

 ray own product did not alter its melting point. 



Phenylhydrazine gives no rise of temperature with allyl formate, 

 but on being kept for a day, an abundant quantity of formylphenyl- 

 hydrazine forms, m. p. 145°. 



With secondary aliphatic amines there is less heat evolved in 

 the action on allyl formate. 



Dimethylamine readily forms dimethylformamide. The action of 

 7 arams diethylamine on 10 grams of allyl formate causes (in about 

 20 minutes) a slow rise to 33°. Diaethylformamide was readily obtai- 

 nable in a pure condition. Dipropylamine (5 grams) mixed in a 

 Weinhold flask with 5 grams of the ester caused a slow rise to 

 35°.5. The dipropylformamide obtained boiled at 211° (corr.). 



Judging from a preliminary experiment, diisopropylamine seems to 

 react less readily; 3 grams of both compounds being mixed, only a 

 slight elevation of temperature was noticed. This reaction deserves 

 in particular a closer study. 



With diisobutylamine the evolution of heat is also trifling; only 

 3° rise 10 grams of each substance being mixed. All the same, a good 

 yield of diisobutylformamide was obtained, which boils at 227° — 228° 

 (corr.) and which, to my knowledge, has not yet been described. 



Methylbenzylformamide (5 grams) with allyl formate (5 grams) 

 gives a rise to 55°. The product formed has not yet been solidified.
