supporting information, p. 2881 - 2884 (2017/07/11)
Tetraarylphosphonium inner-salts (TAPIS) have been designed, synthesized and verified as recyclable and reusable Lewis base catalysts. The resulted TAPIS catalyst has been successfully applied in Michael addition, cyanation and trifluoromethylation reactions.

Ruthenium vinylidene complexes 2a-2c containing indenyl and bidentate dppe ligands can be obtained in efficient yields. Treatment of the cationic ruthenium vinylidene complexes with n-Bu4NOH in acetone yields the neutral cyclopropenyl products (η5-C9H7)(dppe)Ru- CC(Ph)CHR (3) (3a, R = Ph; 3b, R = CN; 3c, R = p-C6H4-CN) via the deprotonation reaction. Reaction of complexes 3a and 3c with Me 3SiN3 (TMSN3) the N-coordinated complexes 4a and 4c can be obtained as stable products. Complex 3b containing CN group at Cγ in the cyclopropenyl ring reacts with TMSN3 yielded the tetrazolate complex 5b. Similar cyclopropenyl products containing indenyl and two triphenylphosphine ligands 3′ can also be synthesized. Reaction of complex 3b′ with TMSN3 also yielded the tetrazolate complex as the major product. And the minor products are [Ru]-N3 and organic compound 6b. Reaction of 3a′ and 3c′ with TMSN3 yielded [Ru]-N3. The corresponding organic products can also be obtained via the N3- attacking the metal center in the N-coordinated complexes 4a′ and 4c′.
