摘要:
Novel urethane derivatives of polymethyl biphenyl useful as fungicides and also having insecticidal, miticidal and nematocidal activities are disclosed. These products are prepared by reacting the appropriate alkyl or aryl chloroformate with the appropriate amino polymethylbiphenyl at temperatures of 0 to 35*C. to produce the corresponding urethane derivatives of polymethyl biphenyl.

Novel urethane derivatives of polymethyl biphenyl useful as fungicides and also having insecticidal, miticidal and nematocidal activities are disclosed. These products are prepared by reacting the appropriate alkyl or aryl isocyanate with the hydroxy polymethylbiphenyl at temperatures of 0* to 35*C. to produce the corresponding urethane derivatives of polymethyl biphenyl.
摘要:
A process for preparing novel carboxylic acids which process comprising heating aromatic compounds which do not readily undergo electrophylic substitution with 3-carboxyphenyl sulfonyl chloride at a temperature of about 150* to 350* C. for a period of about 0.25 to 24 hours in the mole ratio of 4:1 to 20:1.
