Electric Literature of 162318-34-5, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 162318-34-5, name is 5-Ethynyl-2,2′-bipyridine.

Synthesis of luminescent alkynyl gold metalaligands containing 2,2?-bipyridine-5-yl and 2,2?:6?,2?-terpyridine-4-yl donor groups
[AuCl(SMe2)] reacts with HC?CR (R = bpyl = 2,2?-bipyridine-5-yl (1), phtpyl = phenyl-4-(2,2?: 6?,2?-terpyridine-4-yl) (2)) and NEt3 (1:1:3) to afford the polymers [Au(C?CR)]n (R = bpyl (3), phtpyl (4)). The new alkyne HC?Cphccbpyl (5, phccbpyl = 4-C6H4C? CbPyl) has been prepared by Sonogashira coupling of 4-Me3SiC? CC6H4I and 1 followed by desilylation of the resulting alkyne 4-Me3SiC?Cphccbpyl. The alkynyl Au(I) complexes [Au(C?CR)L] (R = bpyl, L = PPh3 (6), PTol3 (7, Tol = 4-MeC6H4), PEt3 (8); R = phtpyl, L = XyNC (9), PPh3 (10); R = phccbpyl, L = PPh3 (11)) have been prepared by reacting: (1) 3 or 4 with L or (2) the corresponding alkyne 1,2, or 5 with [Au(acac)(PPh3)] (acac = acetylacetonato). The reaction of 3 or 4 with diphosphines gives [(Au(C?CR) }2(muPh 2P(CH2)XPPh2)] (R = bpyl, x = 1 (12), 2 (13), 4 (14), 10 (15); R = phtpyl, x = 10 (16)). ESI mass spectrometric studies show that complexes 12-14 are in equilibrium with the salts [Au 3(C?Cbpyl)2(muPh2P(CH2) xPPh2)2][Au(C?Cbpyl)2], although only when x = 1 (17) was a significant concentration of the salt detected by NMR spectroscopy and isolated. The anionic complexes PPN[Au(C?CR)2] (R = bpyl (18), phtpyl (19), or phccbpyl (20)) have been prepared by reaction of the corresponding alkynes with PPN[Au(acac)2]. Complexes 6, 10, 13, 14, 17, and 18 have been characterized by single-crystal X-ray diffraction studies. The alkynyl complexes are luminescent at room temperature, displaying dual emissions.
