A bifunctional ligand precursor (4-ethynylphenyl)diphenyl phosphine was synthesized and used for constructing silver acetylide frameworks. Its reaction with Ag(I) in the presence of triethylamine afforded silver acetylide [AgL]n, in which L = Ph2P-C6H4-4-C[tbnd]C?could act as a bifunctional ligand bearing both phenylethynide and phosphine binding sites for Ag(I). Reactions of [AgL]nand AgCF3CO2under different conditions gave four silver acetylides. They are [Ag18L8(CF3COO)6(HCO3)4(DMF)4]n(1, DMF = dimethylformamide), [Ag20L8(CF3COO)12(DMF)6]n(2), [Ag17L6(CF3COO)9(HCO3)2]n(3), and [Ag17L6(CF3COO)9.58(HCO3)1.42]n(4). Crystallographic studies revealed that complex 1 crystallized in the triclinic space group P1ˉ with a = 14.1252(9) ?, b = 18.6012(12) ?, c = 25.2137(17) ?, α = 108.340(2)°, β = 95.386(2)°, γ = 95.535(2)°, V = 6204.6(7) ?3, and Z = 1. Complex 2 crystallized in the monoclinic space group C2/c with a = 48.046(4) ?, b = 14.1860(10) ?, c = 34.943(2) ?, β = 98.315(3)°, V = 23,566(3) ?3, and Z = 4. Complex 3 crystallized in the triclinic space group P1ˉ with a = 15.5690(7) ?, b = 16.7707(8) ?, c = 34.0810(16) ?, α = 93.4040(10)°, β = 100.3690(10)°, γ = 94.8250(10)°, V = 8697.1(7) ?3, and Z = 2. Complex 4 crystallized in the triclinic space group P1ˉ with a = 15.5396(6) ?, b = 16.7595(7) ?, c = 34.0225(15) ?, α = 93.8140(10)°, β = 100.1000(10)°, γ = 94.9770(10)°, V = 8660.2(6) ?3, and Z = 2. The presence of Ag(I)–ethynide, Ag(I)–P and Ag(I)–Ag(I) bonding interactions makes all four silver acetylides to have two- and three-dimensional framework structures with unusual high-nuclearity silver cluster building blocks.

The use of three orthogonally tagged phosphine reagents to assist chemical work-up via phase-switch scavenging in conjunction with a modular flow reactor is described. These techniques (acidic, basic and Click chemistry) are used to prepare various amides
