A gold complex containing 2,7-bis(mesitylimidazolylidenyl)naphthyridine (NHC-NP) has been synthesized. Thus, reaction of [{Ag3(NHC-NP) 2}(PF6)3] with [Au(Me2S)Cl] provided an unusual digold complex bridged by two NHC-NP, forming a 20-membered dinuclear metallacycle [{Au2 (NHC-NP) 2Cl2}-(PF 6)2] (2) in high yield. This complex was characterized by spectroscopic and elemental analysis. This gold complex is active for the hydrolysis of 2,2,5-trimethyl-1,3-dioxane-5-methanol and can be recycled without losing the activity.

Paragraph 0008; 0075-0078, (2017/06/02)
The invention relates to a method for preparing trimethylolethane through a continuous condensation hydrogenation method. According to the method, a condensation reaction still for achieving a continuous hydroxy aldehyde addition reaction of an impinging stream reactor, a gas-liquid-solid three-phase drip bed hydrogenation reactor and a bubbling type fluidized bed hydrogenation reactor are involved, and the two hydrogenation reactors are operated in series and contain a novel nickel hydrogenation catalyst and a main ingredient copper-chrome-aluminum-zinc catalyst respectively. It is guaranteed that formaldehyde and propionaldehyde stably generate a 2,2-dihydroxy methyl propyl aldehyde intermediate under organic weak alkali through the continuous impact steam aldol condensation reactor, generated byproducts are reduced, two hydrogenation reactions of different structures have the advantages of being high in conversion rate, simple in process, high in product purity, good in high temperature stability and the like, and the final yield of trimethylolethane can reach 95% or above.
