New neutral and anionic alkynylgold(I) complexes via new synthetic methods. Crystal and molecular structures of [Au(C≡CSiMe3)(CNtBu)], and [Au(C≡CR)PR′3] (R′ = cyclohexyl, R = CH2Cl, CH2Br; R′ = Ph, R = SiMe3, tBu)

[(PPh3)2N][Au(acac)2] (acac = acetylacetonate) reacts with terminal alkynes RC≡CH to give [(PPH3)2N][Au(C≡CR)2] (R = H, tBu, SiMe3, CH2X (X = Cl, Br, OH)) complexes. The reactions between [(PPh3)2N][Au(C≡CH)2] and [(PPh3)2N][AuX2] (X = Cl, Br, I) give [(PPh3)2N][Au(C≡CH)X] complexes. Neutral mononuclear [Au(C≡CR)(NHEt2)] (R = SiMe3, tBu), [Au(C≡CR)(PR′3)] (R = H, R′ = Ph, C6H4OMe-4; R = CH2Cl, CH2Br, CH2OH, R′ = Cy = cyclohexyl; R = SiMe3, R′ = Ph, C6H4OMe-4, Cy; R = tBu, R′ = Ph, Cy, C6H4OMe-4), [Au(C≡CR)(CNtBu)] (R = SiMe3, tBu), and [Au(C≡CR){C(NHtBu)(NEt2)}] (R = H, SiMe3, tBu) or dinuclear [(AuL)2{μ-C≡C(CH2)5C≡C)] (L = PPh3, CNtBu, C(NHtBu)(NEt2)) are obtained via a variety of synthetic methods: (i) reaction between [(PPh3)2N][Au(C≡CH)2] and [Au(PR3)2]ClO4, (ii) reaction of terminal alkynes with [Au(acac)(L)], (iii) reaction of [AuClL] complexes with terminal alkynes in diethylamine, (iv) substitution reactions (e.g., [Au(C≡CR)(NHEt2)] + PR′3), (v) reaction of diethylamine with alkynyl isocyanide derivatives to give alkynylcarbene complexes. The crystal structures of [(PPh3)2N][Au(C≡CCH2OH)2], [Au(C≡CSiMe3)(CNtBu)], and [Au(C≡CR)(PR′3)] (R′ = Cy, R = CH2Cl, CH2Br; R′ = Ph, R = SiMe3, tBu) were determined.
