Tetramethyl stannane

The group at Tokyo Institute of Technology have also examined the electroreduction of methyl halides at a reactive tin cathode [198]. This is a different type of electrochemical system in which the cathode is a reactive metal. A surface intermediate is formed on the electrode which reacts to give either a three-electron dimeric distannane or a four-electron tetramethyl stannane, as shown in Scheme 9. 

Barrel and Platt have studied the photolysis of tetramethyl-stannane, trimethyltinhydride and hexamethylditin vapours and examined the alkane reaction products on Poropak at 50°C or Apiezon at lOO C,... 

Hybridized carbon attached directly to a metal is less reactive than sp2- or sp-hybridized carbon in Pd-catalyzed reactions. Tetramethyl- or tetrabutyl-stannane can be used for the preparation of... 

Wrackmeyer etal. described how (Z)-2-chloro-(dimethyl)stannyl-3-diethylborylpent-2-ene 44, obtained by reacting chlorodimethyl(prop-l-ynyl)stannane with triethylborane, isomerizes into (Z)-3-chloro-(dimethyl)stannyl-2-diethyl-borylpent-2-ene 45 when treated in THE with powdered sodium amide at 65 °C (Scheme 3) <2002ZN1251>. Pure 3,5-diethyl-l,l,2,4-tetramethyl-2,3-dihydro-l//-l,3-stannaborole 29a was obtained by the reaction of 45 in hexane with a suspension of lithium diisopropylamide (LDA) in toluene at —78°C. The reaction goes to completion by allowing the reaction mixture to reach room temperature and then by briefly heating to reflux. The yields of compounds 45 and 29a were 78% and 93%, respectively.
