PhSnMe3

PhSnMe3, also known as phenyltrimethylstannane, is an organotin compound in which tin is bonded to one phenyl group and three methyl groups. Its molecular formula is C9H14Sn. The tin center is tetravalent and the molecule has a roughly tetrahedral arrangement of Sn–C bonds.

In naming and classification terms, PhSnMe3 is a tetravalent organostannane with four carbon substituents around tin: one aryl (phenyl) and three alkyl (methyl) groups. Compounds of this type are studied within organotin chemistry as potential precursors to aryl tin species used in a range of transformations.

Applications and reactivity: PhSnMe3 can serve as a synthetic building block and as a source of aryl tin moieties in various transformations. In cross-coupling and transmetallation contexts, organotin reagents are used to transfer carbon groups to metal centers under catalytic conditions. Although more common arylstannanes employ different alkyl substituents (for example, R3SnBu), PhSnMe3 can participate in Stille-type or related processes under suitable conditions, depending on the catalyst system and reaction setup.

Synthesis: General organotin methodologies apply, such as installation of the phenyl group onto a trimethylstannyl fragment or transmetallation routes from related tin reagents. The exact procedure can vary between laboratories and is described in the organotin literature for specific synthetic goals.

Safety: Organotin compounds can be toxic and environmentally persistent. Handling should follow standard laboratory safety practices, including the use of gloves, eye protection, appropriate ventilation, and proper waste disposal.
