Usage

Description

HBBPC, or 4,4'-Hexafluorisopropylidene diphenyl bisphenoxy phosphate, is a flame retardant and plasticizer that is widely used in various industrial applications. It is recognized for its effectiveness in enhancing the flame resistance of plastics and polymers, which makes it a popular choice in the production of electronic components, cables, and construction materials. HBBPC is also valued for its non-migration properties and high thermal stability as a plasticizer. Despite its benefits, there are potential health and environmental concerns associated with its use, prompting increased scrutiny and research into its potential risks. This has led to a growing interest in developing safer alternatives for flame retardant and plasticizing applications.

A New Synthetic Method for the 2-Substitution of N-Unsubstituted Benzimidazoles: Formaldehyde as a Versatile Protecting Agent for Heterocyclic NH

N-Unsubstituted benzimidazoles 1 are readily converted in a one-pot sequence into 2-substituted derivatives 2 with good overall yields.N-Protection with formaldehyde and lithiation with lithium N,N-diisopropylamide (LDA), n-butyllithium, or tert-butyllithium gives the dilithiohemiaminals 6, which readily react with a range of electrophiles at the 2-carbon.The 2-substituted 1-(lithioxymethyl)benzimidazoles 7 undergo smooth acid-catalyzed dehydroxymethylation under mild conditions to give N-unsubstituted 2-substituted benzimidazoles 2.
