I am not sure there's scientific research (probably, can't be arsed to look), but hot solvent (even if brief) is likely to dissolve something in the process. There's little in a biochemistry lab that can't be improved with hot solvents. Certainly a splash of wine loosens up the tasty gunk on the bottom of the pan far better than the equivalent splash of water. Plus the faster evaporation seems to ensure food ends up less mushy.
You can use a splash of vodka for more alcohol, and there's a few recipes that specifically request vodka. Vermouth and brandy are common but add a lot more of their own flavour. Admittedly, drinking the remaining 2/3rds of the brandy bottle is more challenging, but hey, it's open.
But anyway, given the relative boiling points of ethanol and water, even a few minutes of simmering will reduce the alcohol content to nil. I have a recipe where I marinade chicken in half a bottle of white wine, lots of garlic and coriander seeds, some lemon juice overnight and then slow-cook the lot for at least 8 hours with the rest of the bottle of wine, and at the end reduce all the wine to a sticky sauce and combine with yoghurt. Then I eat it all before anyone dibs it. It's lushly decadent but doesn't, per se, taste of wine.
I'm not sure about replacing wine with vinegar, that makes things taste of vinegar (boiling point of ethanol is about 78 degrees, acetic acid 118 degrees Celsius). I wouldn't use it in place of wine
