底物范围

适用范围
Ethene is used as the representative alkene; addition of hydrogen iodide across a C=C bond forms an iodoalkane.
来源说明
Unsymmetrical alkenes can show regioselectivity; this route records the HI branch of alkene hydrohalogenation separately from HCl and HBr.

    Supports HCl, HBr, and HI reacting with alkenes by polar electrophilic addition to form alkyl halides; this route uses the HCl branch to form chloroalkanes and keeps Markovnikov regioselectivity as a scope boundary for unsymmetrical alkenes.
