Problem to be Solved
It is intended to provide an industrially preferable fluoroalkylating agent and use thereof.
Solution
The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R
1
is a C1 to C8 fluoroalkyl group; R
2
and R
3
are each independently a C1 to C12 alkyl group or the like; Y
1
to Y
4
are each independently a hydrogen atom, a halogen atom, or the like; and X
−
is a monovalent anion.
A compound of the general formula (3): R
4
—S—R
1
having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R
4
—S—Z wherein R
4
is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).
A very efficient and reusablecatalyst has been developed for the on-waternucleophilicsubstitution of alkyl halides and tosylates with azide or thiocyanate in excellent to quantitative yields. The reaction proceeds smoothly and cleanly without any organic cosolvent or other adductive, and the brush can be reused at least 10 times without noticeable loss of the catalytic activity. The high efficiency

ABSTRACT A series of new alkyl or aryl sulfanyltetrazole derivatives containing dithiocarbamate moiety (5a–6e) were synthesized. The structures of the compounds were characterized by IR, 1H NMR, 13C NMR spectra, and elemental analysis data. The present study examines the antibacterial potential of novel synthetic sulfanyltetrazole compounds against clinically important gram-positive and -negative strains
In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphoruspentasulfide (P2S5) in refluxing toluene. The method avoids the use of expensive and hazardous transition metals and harsh reducing agents, as required by reported methods, and provides an attractive alternative to the existing methods for the conversion of organic
