1.
Five- and six-membered silacycloalkanes of type\(\begin{array}{*{20}c} {R(CH_2 Cl)Si(CH_2 )_n - (R = CH_3 , Cl)} \\ {\begin{array}{*{20}c} | & | \\ \end{array} } \\ {\_\_\_\_} \\ \end{array}\) undergo rearrangement under the influence of catalytic amounts of aluminum chloride, with an expansion of the ring and the formation of products of type\(\begin{array}{*{20}c} {R ClSi(CH_2 )_{n + 1} - } \\ {\begin{array}{*{20}c} | & | \\ \end{array} } \\ {\_\_\_\_} \\ \end{array}\).

2.
The indicated new transformation can serve as a method for the preparation of silacycloheptanes.
