ABSTRACT:
1,1-dimethyl-2,3-benzo-1-sila-2-cyclobutene was synthesized from 2-bromobenzyl bromide through a modified Grignard procedure, which resulted in a higher (41%) than literature reported yield (35%). An alternative approach with a much less costly 2-chlorobenzyl chloride as starting material is also disclosed. In addition, new di-benzosilacyclobutene compounds were synthesized with our modified Grignard procedure. The compounds are useful as coating materials for surfaces, and when applied to metallic surfaces, can be used neat.
