Paragraph 0145; 0150-0151; 0198-0199; 0201; 0206-0207, (2020/07/21)
The invention relates to an N-para-sulfonium salt substituted pyrazoline derivative shown as the following formula (I) in the specification, a photocurable composition, and a preparation method of theN-para-sulfonium salt substituted pyrazoline derivative shown as the following formula (I). The N-para-sulfonium salt substituted pyrazoline derivative shown as formula (I) has good absorption at a wavelength of 350nm or above, and compared with a 5-substituted sulfonium salt, the N-para-sulfonium salt substituted pyrazoline derivative has the advantages of simpler and more convenient molecule synthesis steps and reduced cost of raw materials, and is more suitable for industrial production and application.

Aryl-furyl substituted pyrazolines 2a-c and 4a-c were prepared by the reaction of α,βunsaturated carbonyl compounds with hydrazine or phenyl hydrazine. N-chloroacetyl derivatives 3a-c were obtained by the N-acetylation of 2a-c. The antibacterial activities of synthesized pyrazolines were examined by employing the disk-diffusion technique. All synthesized compounds showed antibacterial effects in 1200 μg concentration.
