Hexamethylcyclotrisiloxane, also known as D3 and D3, is the organosilicon compound with the formula Шаблон:Chem2. It is a colorless or white volatile solid. It finds limited use in organic chemistry. The larger tetrameric and pentameric siloxanes, respectively octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane, are of significant industrial interest,[1] whereas 1,000–10,000 tonnes per year of the trimer is manufactured and/or imported in the European Economic Area.[2]

Structure and reactions

Hexamethylcyclotrisiloxane adopts a planar structure and is considered strained.[3][4] It reacts with organolithium reagents to give, after hydrolysis, dimethylsilanols:
