S-methyl 3-furfurylidene-2-methyl-dithiocarbazate and its use as a fungicide

#This invention relates to a compound having fungicidal activity, and to processes for controlling or eradicating fungi using this compound.

#Accordingly we provide the compound S-methyl 3-furfurylidene-2-methyl-dithiocarbazate.

#The compound may be made by any of the following methods: ##STR1##

#Our invention is illustrated by, but no way limited to, the following examples.

#This example describes the preparation of S-methyl 3-furfurylidene-2-methyl-dithiocarbazate according to the equation i.e. ##STR2##

#Acetic acid (5 mls) was added to 50 ml of ethanol, this solution was warmed, and 2.7 g of S-methyl-2-methyl-dithiocarbazate was added with stirring. Furfuraldehyde (1.9 g) was added and a crystalline precipitate was obtained which was re-crystallized from ethanol yielding 3.3 g of S-methyl 3-furfurylidene-2-methyl-dithiocarbazate melting at 98.degree. C. The identity of the product was confirmed by mass spectrometry. On further recrystallization from ethanol and charcoal the melting point increased to 104.degree. C.
