乙炔基(苯基)碘鎓四氟硼酸盐[乙炔基化试剂] - Introduction

Ethynylphenyliodonium tetrafluoroborate, also known as ethynylating reagent, is an organometallic compound with the chemical formula C6H5C2I(BF4). The following is a description of its nature, use, preparation and safety information:

Nature:
Ethynylphenyliodonium tetrafluoroborate is a solid, white crystal at room temperature, soluble in organic solvents such as dimethyl sulfoxide (DMSO) and acetonitrile. It has strong nucleophilic substitution properties and can be introduced into functional groups by electrophiles such as substitutional halogen compounds.

Use:
Ethynylphenyliodonium tetrafluoroborate is commonly used in organic synthesis, especially in acetylene coupling reactions in C- C bond formation reactions. It can be used to synthesize organic compounds containing alkynyl groups, such as alkynes, alkynols, etc. The compounds can also be used as visible light catalysts for photochemical and photocatalytic reactions.

Preparation Method:
The preparation of ethynylphenyliodonium tetrafluoroborate is usually obtained by chemical reaction. The specific procedure involves reacting phenylbenzoborate with zinc iodide to form sodium ethynylphenyl, followed by reaction with tetrafluoroboric acid to give ethynylphenyliodonium tetrafluoroborate.

Safety Information:
Ethynylphenyl iodonium tetrafluoroborate needs to be safe during operation and storage. It has an irritating effect on the skin, eyes and respiratory system, and direct contact should be avoided. Use with appropriate personal protective equipment, such as lab gloves, goggles and protective masks. When in use to comply with the appropriate laboratory practices, and properly stored, avoid contact with inflammables and oxidants.
