Content

Getting

Effect of ethylmagnesium bromide on tin dichloride :

{\mathsf {SnCl_{2}+2Mg(C_{2}H_{5})Br\ {\xrightarrow {}}\ Sn(C_{2}H_{5})_{2}+MgCl_{2}+MgBr_{2}}}

{\ displaystyle {\ mathsf {SnCl_ {2} + 2Mg (C_ {2} H_ {5}) Br \ {\ xrightarrow {}} \ Sn (C_ {2} H_ {5}) _ {2} + MgCl_ { 2} + MgBr_ {2}}}}

Recovery of diethyltin chloride by zinc :

{\mathsf {Sn(C_{2}H_{5})_{2}Cl_{2}+Zn\ {\xrightarrow {}}\ Sn(C_{2}H_{5})_{2}+ZnCl_{2}}}

{\ displaystyle {\ mathsf {Sn (C_ {2} H_ {5}) _ {2} Cl_ {2} + Zn \ {\ xrightarrow {}} \ Sn (C_ {2} H_ {5}) _ {2 } + ZnCl_ {2}}}}

Physical Properties

Diethyl tin is a yellow liquid, almost insoluble in water, but soluble in organic solvents . Boils at a temperature of about 150 ° C, with further heating decomposes.

Chemical Properties

Reacts with chlorine :

{\mathsf {Sn(C_{2}H_{5})_{2}+Cl_{2}\ {\xrightarrow {}}\ Sn(C_{2}H_{5})_{2}Cl_{2}}}

{\ displaystyle {\ mathsf {Sn (C_ {2} H_ {5}) _ {2} + Cl_ {2} \ {\ xrightarrow {}} \ Sn (C_ {2} H_ {5}) _ {2} Cl_ {2}}}}

Oxidized on the air:

{\mathsf {2Sn(C_{2}H_{5})_{2}+O_{2}\ {\xrightarrow {}}\ 2Sn(C_{2}H_{5})_{2}O}}

{\ displaystyle {\ mathsf {2Sn (C_ {2} H_ {5}) _ {2} + O_ {2} \ {\ xrightarrow {}} \ 2Sn (C_ {2} H_ {5}) _ {2} O}}}

Decomposition occurs with the formation of tetraethyl tin :

{\mathsf {2Sn(C_{2}H_{5})_{2}\ {\xrightarrow {T}}\ Sn(C_{2}H_{5})_{4}+Sn}}

{\ displaystyle {\ mathsf {2Sn (C_ {2} H_ {5}) _ {2} \ {\ xrightarrow {T}} \ Sn (C_ {2} H_ {5}) _ {4} + Sn}} }

Interacts with chloroethane :

{\mathsf {Sn(C_{2}H_{5})_{2}+C_{2}H_{5}Cl\ {\xrightarrow {}}\ Sn(C_{2}H_{5})_{3}Cl}}

{\ displaystyle {\ mathsf {Sn (C_ {2} H_ {5}) _ {2} + C_ {2} H_ {5} Cl \ {\ xrightarrow {}} \ Sn (C_ {2} H_ {5} ) _ {3} Cl}}}
