  • Publication number: 20220411446
    Abstract: Organotin compounds are presented that are represented by the formula RSnL3, wherein R is a deuterated hydrocarbyl group and L is a hydrolysable ligand. Two different synthesis techniques are described for synthesizing these compositions. A first method involves reacting a primary halide hydrocarbyl compound (R—X, where X is a halide atom) with an organometallic composition comprising SnL3 moieties associated with metal cations M, where M is an alkali metal, alkaline earth metal, and/or pseudo-alkaline earth metal (Zn, Cd, or Hg), and L is either an amide ligand resulting in an alkali metal tin triamide compound or an acetylide ligand resulting in an alkali metal tin triacetylide, to form correspondingly a monohydrocarbyl tin triamide (RSn(NR?2)3) or a monohydrocarbyl tin triacetylide (RSn(C?CRs)3).

  • Publication number: 20220064192
    Abstract: Synthesis reactions are described to efficiently and specifically form compounds of the structure RSnL3, where R is an organic ligand to the tin, and L is hydrolysable ligand or a hydrolysis product thereof. The synthesis is effective for a broad range of R ligands. The synthesis is based on the use of alkali metal ions and optionally alkaline earth (pseudo-alkaline earth) metal ions. Compounds are formed of the structures represented by the formulas RSn(C?CSiR?3)3, R?R?ACSnL3, where A is a halogen atom (F, Cl, Br or I) or an aromatic ring with at least one halogen substituent, R?R?(R??O)CSnL3 or R?R?(N?C)CSnZ3.
