What is para toluene sulphonyl chloride?
4-Toluenesulfonyl chloride is an organic compound with the formula CH¿¿¿C¿¿¿H¿¿¿SO¿¿¿Cl. Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride functional group. Features: Precise composition. Hygienic.
What is the structure of para toluene sulfonyl chloride?
Formula and structure: The tosyl chloride chemical formula is C7H7ClO2S and its molar mass is 190.15 g mol-1. The molecule is formed by one toluene core, which has in para position a sulfonyl chloride. The structure is completely planar, due to most of the atoms need a sp2 hybridization to form the double bonds.
Is tosyl chloride soluble in water?
It is insoluble in water, soluble in alcohol, ether and benzene. P-toluenesulfonyl chloride is also known as 4-methyl-benzenesulfonyl chloride, 4-toluenesulfonyl chloride.
What is tosyl chloride soluble in?
Abstract. Alternate Names: tosyl chloride. Physical Data: mp 67–69 °C; bp 146 °C/15 mmHg. Solubility: insol H2O; freely sol ethanol, benzene, chloroform, ether.
What does TsCl do in a reaction?
Tosyl chloride (TsCl) is usually used as an activating group for primary alcohols. Due to its relatively large volume and the lower reactivity of secondary and tertiary alcohols, it usually doesn’t come into them, being selective to primary alcohols in most of the cases.
Why is pyridine more nucleophilic than alcohol?
A tertiary amine and not primary/secondary is used, because amines are in general stronger nucleophiles than alcohols, but tertiary amines would give quite electrophilic products themselves. Pyridine is used, because nitrogen in it is in sp2 state, resulting in significantly lowered nucleophilicity.
What is tosylate used for?
Tosylates are good substrates for substitution reactions, reacting with nucleophiles in much the same way as alkyl halides. The advantage of this method is that the substitutions reactions are not under the strongly acidic conditions. Used mostly for 1o and 2o ROH (hence SN2 reactions).
