How is a semicarbazone made?
In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide.
Is cyclohexanone a primary alcohol?
Cyclohexanol: A secondary alcohol of molecular formula C6H14O in which the hydroxyl group is bonded to a cyclohexane ring.
What is semicarbazone with example?
What class of alcohol is cyclohexanol?
secondary alcohol
Cyclohexanol is an alcohol that consists of cyclohexane bearing a single hydroxy substituent. The parent of the class of cyclohexanols. It has a role as a solvent. It is a secondary alcohol and a member of cyclohexanols.
How toxic is cyclohexanone?
The toxicity of cyclohexanone has been rarely documented in humans and experimental animals. Human exposure by inhalation causes irritation to the respiratory system (5). Inhalation of large quantities of cyclohexanone can cause nervous system depression, and irritate the eye and skin (1).

What is cyclohexane used for?
Most cyclohexane goes into the production of intermediates for nylon, which has a variety of common applications such as clothing, tents and carpets as well as thermoplastics. Cyclohexane is also used as a solvent in chemical and industrial processes and recently has been substituted for benzene in many applications.
How do you make semicarbazone?
Preparation of acetone semicarbazone (acetone, semicarbazone, acetonesemicarbazone, 2-propanone, semicarbazone) A solution of 1.0 g of semicarbazide hydrochloride and 1.5 g of crystallized sodium acetate in 10 ml of water is prepared. 1 ml of acetone is added and the reaction mixture is shaken vigorously.
What is α-oxo semicarbazone chemistry?
α-Oxo semicarbazone chemistry is the condensation reaction between α-oxo aldehyde-functionalized ligands and a semicarbazone-functionalized surface (Fig. 5.9 ).
What does cyclization of the semicarbazone (216) give?
Cyclization of the semicarbazone (216) under basic conditions delivered benzopyrano-1,2,4-triazin-3-one ( 132) (90%). A similar reaction of the thiosemicarbazone ( 217) gave the benzopyrano-1,2,4-triazin-3-thione ( 151) (91%).
What is a semicarbazone?
In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. They are classified as imine derivatives because they are formed from the reaction of an aldehyde or ketone with the terminal -NH 2 group of semicarbazide, which behaves very similarly to primary amines .
How to prepare semicarbazones and thiosemicarbazone?
J. Stephen Clark, in Comprehensive Organic Functional Group Transformations, 1995 Semicarbazones and thiosemicarbazones can be prepared by treatment of a ketone or aldehyde with semicarbazide or thiosemicarbazide (Scheme 16 ).
