Abstract

Lewis-base-stabilized silicon species in the zero oxidation state are crucial for transforming elemental silicon into valuable compounds. The synthesis of a cyclic tetraatomic silicon(0) cluster, stabilized by four-membered cyclic alkyl(amino) carbenes, is reported. It is a versatile one, two, or four silicon atom source, demonstrating cluster isomerization or fragmentation.
