Abstract: By synthesis the following were prepd.: 2-benzothiazolyl N,N-dimethylcarbamate (I), m. 106.5-9.0°; S-(2-benzothiazolyl) N,N-dimethylthiocarbamate (II), m. 105.5-8.0°; 2-benzothiazolyl N,N-diphenylcarbamate (III), m. 168-9.5°; 2-benzothiazolyl) N,N-diethylcarbamate (IV), m. 165-8°; S-(2-benzothiazolyl) N,N-diethylthiocarbamate (V), m. 91-3°; S-(2-benzothiazolyl) N,N-diphenylthiocarbamate (VI), m. 157.5-8.5°; O-(2-benzothiazolyl) N,N-diethylthiocarbamate (VII), m. 98-100.5°; 2-benzothiazolyl N,N-dimethyldithiocarbamate (VIII), 120.5-23°; 4-methyl-7-coumarinyl, N,N-dimethylcarbamate (IX), 123-4.5°; 4-coumarinyl N,N-dimethylcarbamate (X), m. 97-7.5°; bicyclo [2.2.1] hept-5-en-2-ylmethyl N,N - dimethylcarbamate (XI), b4 118-20°, d20 1.0580,n20D 1.4860; bicyclo[2.2.1]-hept-5-en-2-ylmethyl N,N-diethylcarbamate (XII), b0.25 109-13°, d20 1.0106, n20D 1.4175. III, IV, VII, XI, and XII are new compds. I to X showed very little insecticide toxicity except XI and XII which at higher concn. (5%) were more effective than (p-ClC₆H₄)₂CHCCl₃.
