32745-69-0 Usage
General Description
3-(4-tert-Butylphenyl)-1,1-dimethylurea, also known as diuron, is a white crystalline solid widely used as a pre-emergent herbicide in agriculture and horticulture. It works by inhibiting photosynthesis in plants, making it effective at controlling the growth of a wide range of weeds. Diuron is non-selective, meaning it can affect both broadleaf and grassy weeds. It is relatively stable in soils, making it a long-lasting herbicide, and it is also known to persist in water and have potential environmental impacts. Due to its potential negative effects on aquatic and terrestrial ecosystems, the use of diuron is regulated in some countries.
Check Digit Verification of cas no
The CAS Registry Mumber 32745-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,7,4 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 32745-69:
(7*3)+(6*2)+(5*7)+(4*4)+(3*5)+(2*6)+(1*9)=120
120 % 10 = 0
So 32745-69-0 is a valid CAS Registry Number.

Merging C-H activation and alkene difunctionalization at room temperature: A palladium-catalyzed divergent synthesis of indoles and indolines

A palladium-catalyzed 1,2-carboamination through C-H activation at room temperature is reported for the synthesis of 2-arylindoles, and indolines from readily available, inexpensive aryl ureas and vinyl arenes. The reaction initiates with a urea-directed electrophilic ortho palladation, alkene insertion, and ?2-hydride elimination sequences to provide the Fujiwara-Moritani arylation product. Subsequently, aza-Wacker cyclization, and ?2-hydride elimination provide the 2-arylindoles in high yields. Intercepting the common -alkyl-Pd intermediate, corresponding indolines are also achieved. The indoline formation is attributed to the generation of stabilized, cationic -benzyl-Pd species to suppress ?2-hydride elimination.
