The present invention concerns novel compounds of the formula: ##EQU1## wherein R.sub.1 to R.sub.9 have various significances including e.g. alkyl, X and Y include O and S and s, v, w and z are O or whole numbers and Ar.sub.1 is a formyl phenyl radical. The compounds possess insecticidal properties.
本发明涉及新的化合物,其
化学式为:##EQU1## 其中R.sub.1至R.sub.9具有不同的含义,包括例如烷基,X和Y包括O和S,s,v,w和z为O或整数,Ar.sub.1是甲酰苯基基团。这些化合物具有杀虫性能。
