## Abstract Diazoacetonitrile is prepared in one stage from methyleneaminoacetonitrile and added to 2 : 5โ€dimethylhexaโ€2 : 4โ€diene. The resultant mixture of (ยฑ)โ€__trans__โ€ and (ยฑ)โ€__cis__โ€chrysanthemonitrile is hydrolysed to (ยฑ)โ€__trans__โ€chrysanthemamide and to (ยฑ)โ€__trans__โ€chrysanthemic acid. I
