How about just making benzaldehyde from bensyl alcohol? Sure has a nice smell of Amaretto liquor  .

combining HCl or NaOH with acetone and letting it sit for a while (maybe some sunlight for good luck)
forms an oily compound, phorone or something like it, i remember long ago i had wiped some of this off on a piece of paper towel and on a hot summer
day it was drying near a window and as i woke back up again it was the most beautiful aroma ive ever come across
personally i really like the smell of resorcinol, but i believe its mostly made by extraction from exotic wood barks

Sounds like a mixture of phorone and mesityl oxide, both products of acetone self-condensation. The former has a floral smell, the latter is more
sweet.

SO I made 2-hydroxynaphthaldehyde by the reaction of chloroform with basic naphthol. Pain in the neck to purify without vacuum distillation, and
mostly full of purple impurities, but it smells nice.
I'd like to convert some of it to the ethyl or methyl ether (either with ethyl bromide/KOH, as for ethoxynaphthalene, or with methanol/KHSO4, as for
methoxynaphthalene). Will the aldehyde group stand up to and/or prevent these reactions? I ask because I've never managed to alkylate
salicaldehyde.....

Interesting, what's its smell? Similar to vanillin? I made only methyl, ethyl, allyl ethers of 2-naphthol where methyl and ethyl are solids and have scents similar to orange but different than limonene (they resemble me soaps
of my childhood of Na palmitate type, but not the soap scent itself, just the additives added to soaps). Allyl is liquid and odorless.

No, it was very fruity- more like methyl anthranilate. Definitely grape, although it might have tricked my brain into thinking of grapes by the
aforementioned purple impurities.

Are the purple impurities oxidation products of naphthol? Complex with Fe3+ ? My naphthol was pale yellow/brown as solid and quite dark after
dissolving, but the ether product was easy to purify by steam distillation. The steam distillation was not true steam distillation, it was just a lazy
hydrodistillation - one distillation round bottomed flask with water as well the product and dropping funnel to add water which distilled out. I
reused condensed water to refill dropping funnel as the product was slightly soluble in water and I distilled significant volumes of water.

No idea. I'll probably try steam distillation next time I try it. Also extraction with dichloromethane, as naphthol itself isn't very soluble in DCM
(and the aldehyde is).
I'm thinking it would be good to make ethers of, as well as salen-type ligands.

I'm not sure if it has been said yet, but you could make chloroacetone if you're looking for something easy.
It's as simple as bubbling dry Chlorine gas through acetone.
It makes something that has a very strong vapor and was used as a tear gas in WW1.
It's quite potent so be careful when making or handling it.
you could also make a dispersal method for it if you're looking to get gassed. just try not to breathe much in at one time

One more idea, You could make wintergreen it's simple and does not take a whole lot of time, it also smells very good.

What the hell. Is this some kind of joke? How could chloroacetone be considered a pleasant-smelling compound? Clearly you didn't understand the
premise of the thread before you posted (emphasis added by me):

It seems we've been experiencing an epidemic of poor reading comprehension lately... If you're not going to take the time to read and think
beforehand, you shouldn't post.
