Application

Zinc iodide can be used:
  • As an activator to synthesize poly(vinyl methyl ether) via living cationic polymerization. ZnI2 is known to produce living vinyl ether polymerizations.
  • To prepare precursor solutions for lead halide perovskite solar cells. The addition of ZnI2 leads to higher stability against environmental moisture when introduced into perovskite cells.

A new, efficient method has been developed for converting acyl-, arylalkyl- and alkyl-protected glycals into corresponding 2,3-dideoxy-alpha,beta-unsaturated carbohydrate enals utilizing the in situ generated push-pull effect resulting from the synergistic combination of HfCl4 and ZnI2 in catalytic amounts. This new
