Soc. chim., 1904 [31, 31, p.1306) prepares aldehydes by the gradual addition of disubstituted formamides (dissolved in anhydrous ether) to magnesium alkyl haloids, the best yields being obtained by the use of diethyl formamide.

Harries (Ber., 1895, 28, p. 1223) has also shown that as-phenylhydrazino-acetic esters, when heated with formamide and substituted formamides under pressure, yield dihydrotriazines: CO 2 R CO-NR'-CH H2 N(C6H5)NH2 +R'NH CHO --> CH 2 N(C 6 H 5) IV The phen-a-triazines are yellow-coloured crystalline compounds of a somewhat basic character.
