The indium-mediated allylation of trifluoroacetaldehyde hydrate (R = H) or trifluoroacetaldehyde ethyl hemiacetal (R = Et) with an allyl bromide in water yielded a-trifluoromethylated alcohols (Eq. 8.56).135 Lanthanide triflate-promoted indium-mediated allylation of aminoaldehyde in aqueous media generated (i-airiinoalcohols stereoselectively.136 Indium-mediated intramolecular carbocyclization in aqueous media generated fused a-methylene-y-butyrolactones (Eq. 8.57).137 Forsythe and co-workers applied the indium-mediated allylation in the synthesis of an advanced intermediate for azaspiracids (Eq. 8.58).138 Other potentially reactive functionalities such as azide, enone, and ketone did not compete with aldehyde for the reaction with the in situ-generated organo-indium intermediate.

Most of the studies on organo-gallium, indium, and thallium porphyrin complexes have focused on synthesis and properties of the complexes, and rather little attention has been devoted to reaction chemistry. Two areas which have received some attention are the insertion of small molecules (SO2 or CO2) into the metal—carbon bonds and photochemical metal—carbon bond cleavage. The... 

Although photochemically induced cleavage of Al—C bonds in the aluminum porphyrin complexes has been exploited in several applications, relatively little is known about the intimate mechanism of this process. Similar reactivity is observed for the organo-gallium and indium porphyrins, and for these elements...

Another successful synthetic route to indium-metal species is via insertion of organoindium (I) compounds into metal-halide or metal-metal bonds. The organo... 

This type of self-assembly can probably be expected for many other organo-indium derivatives of polyfunctional ligands. 

This section contains references other than those in the main Report, which have been abstracted during the literature search, and are considered relevant to the chemistry described in this Chapter. The references are arranged according to whether they are aluminium, gallium, indium, or thallium organo-metals and then in alphabetical order according to the name of the first author. Where the information has been obtained from Chemical Abstracts, only the abstracts reference number is given. 

An unusual coupling reaction has been found by irradiation of iodio-methylphosphorous with organo stannanes in the presence of indium (iii)halide, which form in situ the actual catalyst.
