Indium and gallium compounds in the oxidation state (III) can be used as Lewis acids in organic transformation reactions. Recently, additional research has been conducted into the lower oxidation states.
A small sample of the type of reactions that have been enabled by indium- and gallium-based catalysts over the last few years are:
- Selective C-C bond formation
- Allylation of carbonyl compounds and imine derivatives – these are important intermediate steps in the synthesis of natural products and other fine chemicals
- Friedel-Crafts acylation of aromatics
- Addition of pyrroles to isatins
- Preparation of chiral amines
- Ring-opening polymerization reactions
- Selective Meerwein-Ponndorf-Verley reduction of aliphatic and aromatic aldehydes

Part 3 of the semiconductor flux series talks about the important cleaning function of fluxes and how thermocompression bonding can help prevent warpage and die tilt.
When looking at the reliability of AuSn solder paste, you need to take a couple of things into consideration, the post reflow alloy composition (off-eutectic) and the correct flux for the application are two of these.
Today's electronics continue to get smaller and smaller, so the traditional type 3 (-200/+325) mesh size might be too large for new scale-ups. This blog post reviews Indium Corporation's capabilities for making smaller AuSn particle sizes.
