Alkyl-, Aryl-, Vinyl-, and Heterosubstituted Organozirconium Compounds. -Selective Nucleophiles of Low Basicity

Article abstract of DOI:10.1002/hlca.19810640532

Solutions of the title compounds are accessible from organolithium reagents and trialkoxyzirconium chloride (equation 2).In contrast to their titanium analogues, vinylzirconium reagents are stable enough to be employed.Generally, organozirconium reagents are highly selective aldehyde and ketone carbonylophiles of exceedingly low basicity (Tables 1, 2, 3 and typical procedure).
