Catalytic Reductive Cleavage of Poly(phenylene sulfide) Using a HydrosilaneThis work was supported financially by the DIC Corporation and the National Institute of Advanced Industrial Science and Technology (AIST).

The solvent-insoluble poly(phenylene sulfide) main chain was reductively cleaved by using triethylsilane as a hydrogen source under palladium/IcHex catalytic conditions. After the reaction, benzene and bis(triethylsilyl) sulfide as a sulfide source were formed efficiently. This method could be operated on a gram scale.

- 14 According to Sigma-Aldrich, Inc, prices of triethylsilane, trimethoxysilane, triethoxysilane, and bis(trimethylsiloxy)methylsilane are 111 USD/mol (ordering scale, 500 g, 99%), 551 USD/mol (ordering scale, 100 g, 95%), 491 USD/mol (ordering scale, 50 mL, 95%), and 156 USD/mol (ordering scale, 250 mL, 97%).

- 17 This gram-scale reductive bond cleavage was performed under xylene reflux conditions (oil bath temperature was 160 °C) in an open flask. Disilyl sulfide 4 was generated in 75% NMR yield, showing that this reaction is also operative without using a closed vessel.
- 18 In the reaction of PPS with 1 equivalent of 2 catalyzed by Singacycle-A1, 6 was observed in 42% yield with benzene (72%) and 4 (9%). These yields were determined based on the amount of 5.

- 20 In addition, we attempted the reaction of di(4-bromophenyl) sulfide with triethylsilane under the present catalytic conditions to compare the reactivity between C–S and C–Br bonds. As a result, the C–Br bond was cleaved mainly. See the Supporting Information.
