This work describes the preparation of a series of platinum-aminocarbene complexes [PtCl{C(N=C a (C 6 R 2 R 3 R 4 R 5 CON b ))=N(H)R 1 }(CNR 1 )] a-b ( 8 - 19 , 65-75% isolated yield) via the reaction of cis -[PtCl 2 (CNR 1 ) 2 ] (R 1 = Cy 1 , t -Bu 2 , Xyl 3 , 2-Cl-6-MeC 6 H 3 4 ) with 3-iminoisoindolin-1-ones HN=C a (C 6 R 2 R 3 R 4 R 5 CON b H) (R 2 -R 5 = H 5 ; R 3 = Me, R 2 , R 4 , R 5 = H 6 ; R 3 , R 4 = Cl, R 2 , R 5 = H 7 ). New complexes 17 - 19 were characterized by elemental analyses (C, H, N), ESI + -MS, Fourier transform infrared spectroscopy (FT-IR), one-dimensional ( 1 H, 13 C{ 1 H}), and two-dimensional ( 1 H, 1 H correlation spectroscopy (COSY), 1 H, 13 C heteronuclear multiple quantum correlation (HMQC)/ 1 H, 13 C heteronuclear single quantum coherence (HSQC), 1 H, 13 C heteronuclear multiple bond correlation (HMBC)) NMR spectroscopy, and authenticity of known species 8 - 16 was confirmed by FT-IR and 1 H and 13 C{ 1 H} NMR. Complexes 8 - 19 were assessed as catalysts for hydrosilylation of terminal alkynes with hydrosilanes to give vinyl silanes, and complex [PtCl{C(N=C a (C 6 H 3 (5-Me)CON b ))=N(H)(2-Cl-6-MeC 6 H 3 )}{CN(2-Cl-6-MeC 6 H 3 )}] a - b ( 18 ) showed the highest catalytic activity. The catalytic system proposed operates at 80-100 °C for 4-6 h in toluene and with catalyst loading of 0.1 mol %, enabling the reaction of a number of terminal alkynes (PhC≡CH, t -BuC≡CH, and 4-( t -Bu)C 6 H 4 C≡CH) with hydrosilanes (Et 3 SiH, Pr 3 SiH, i -Pr 3 SiH, and PhMe 2 SiH). Target vinyl silanes were prepared in 48-95% yields (as a mixture of α/β isomers) and with maximum turnover number of 8.4 × 10 3 . Hydrosilylation of internal alkynes (PhC≡CPh, Me(CH 2 ) 2 C≡C(CH 2 ) 2 Me, and PhC≡CMe) with hydrosilanes (Et 3 SiH, PhMe 2 SiH) led to the corresponding trisubstituted silylated alkenes in 86-94% yields. Initial observations on the mechanism of the catalytic action of platinum-ADC catalysts 8 - 19 suggested a molecular catalytic cycle., Competing Interests: The authors declare no competing financial interest.
