    A process for the preparation of cyclopropane carboxylic acid derivatives of the formula ##STR1## wherein Z is selected from the group consisting of --CN, --COOH and --COOR.sub.1, R.sub.1 is alkyl of 1 to 6 carbon atoms and R.sub.2 and R.sub.3 are alkyl of 1 to 4 carbon atoms or taken together with the carbon atom to which they are attached form a carbon homocycle of 3 to 6 carbon atoms comprising reacting at low temperatures in a solvent in the presence of a strong base a compound of the formula ##STR2## wherein Z has the above definitions and R is alkyl of 1 to 6 carbon atoms or together form a polymethylene of 2 to 3 carbon atoms with a sulfone of the formula ##STR3## wherein R.sub.2 and R.sub.3 have the above definitions and Y is an aromatic group followed by aqueous treatment to obtain a compound of the formula ##STR4## wherein Y, R, R.sub.2, R.sub.3 and Z have the above definitions, reacting the latter at a low temperature in a solvent with a strong base while letting the temperature rise to obtain a compound of the formula ##STR5## wherein R, R.sub.2, R.sub.3 and Z have the above definitions of the cis/trans configuration richer in the trans isomer and either reacting the latter when Z is --CN or --COOR.sub.1 with a strong base in an aqueous media followed by acidification to obtain a compound of the formula ##STR6## wherein R, R.sub.2 and R.sub.3 have the above definitions having the same configuration as the compound of formula V or reacting the compound of formula V or Va with an acid agent in an aqueous media to obtain the corresponding compound of formula I with the same configuration as the compound of formula V or Va and optionally treating the latter with a weak base at room temperature to obtain the compound of formula I with a trans configuration which are valuable intermediates for the preparation of esters of cyclopropane carboxylic acid having elevated insecticidal activity.
    一种制备环丙烷羧酸衍生物的方法,其化学式为##STR1##其中Z选自--CN、--COOH和--COOR.sub.1的群,R.sub.1为1至6个碳原子的烷基,R.sub.2和R.sub.3为1至4个碳原子的烷基或与它们所附着的碳原子形成3至6个碳原子的碳同环,包括在强碱存在下,在溶剂中低温反应化合物##STR2##其中Z具有上述定义,R为1至6个碳原子的烷基或与它们一起形成2到3个碳原子的聚亚甲基,与公式##STR3##其中R.sub.2和R.sub.3具有上述定义,Y是芳香族基,在水处理后得到公式##STR4##其中Y、R、R.sub.2、R.sub.3和Z具有上述定义,在溶剂中低温反应后,让温度升高以得到公式##STR5##其中R、R.sub.2、R.sub.3和Z具有上述定义的顺反异构体,富含反异构体,如果Z是--CN或--COOR.sub.1,则与强碱在水介质中反应,然后酸化以得到公式##STR6##其中R、R.sub.2和R.sub.3具有上述定义,具有公式V的化合物的相同构型,或者与酸剂在水介质中反应,以得到具有公式V或Va相同构型的相应公式I化合物,可选择性地在室温下用弱碱处理后得到具有反构型的公式I化合物,这些化合物是制备具有升高杀虫活性的环丙烷羧酸酯的有价中间体。
