Abstract
 
ASERIES of phosphono-substituted and 5-membered ring ........chromenes were prepared in reasonable yields from the reactions of 3-(p-chlorophenyl-iminomethyl) chromone (1) with diffrent types of the Wittig-Horner reagents 4a-c, 9 in the presence of a base. On the other hand by applying cyanomethylenetriphenylphosphonium chloride 12 and allyltriphenylphosphonium bromide 15 to 1, the corresponding propanenitrile and methylpropenyl chromene derivatives were obtained.
