Haloiminium salt

Haloiminium salts can react with metallates or similarly nucleophilic transition metal complexes to yield heteroatom-substituted carbene complexes (Figure 2.7) [120]. This reaction is closely related to the acylation of metallates with derivatives of carboxylic acids (Section 2.1.1.2). Examples are given in Table 2.5.
