Q: Reaction of cyclohexyl methyl ketone with phosphorus pentachloride

Abcd I would like to know the mechanism of this reaction leading to the formation of a gem dihalide. I am unable to predict how the $\ce{C=O}$ breaks and how the 2 $\ce{Cl}$ atoms replace the oxygen atom. What kind of a reaction is it? Note: This reaction is mentioned on page 310 of Solomon and Fr...

is this reaction taking place in the aqueous or the solid state? Because I have been able to come with a slightly different mechanism for the reaction depicted here as opposed to the one accepted. I had to use water for hydrolysis in one step there, and I also simply used PCl5 per se without making it's ions. I ended up with the final product shown, along with the elimination of HCl and POCl3
If it helps, I could describe my mechanism scheme further

I wonder how they imagine this to happen.

Hi. I wonder what trick do you use for proper typography of e.g. (2R)-butan-2-ol in comments.
… in a post, I use 2<i>R</i>, but none of "<i/>", "*", "_" work for me in comments, even with some trick attempts with ZWSP character.
 
Some invisible unicode characters should work, e.g. U+2060.

… neither. (I exercise below chemistry.meta.stackexchange.com/a/4313/544 )
 
I saw that.
"N,N-Dimethyl-2-(indol-3-yl)glyoxylamide" is still in a wrong order.
2-(indol-3-yl)-N,N-dimethylglyoxylamide would be a bit better.
Nevertheless, your PIN is correct.
 
I know, I just intended to do minimal edit for "deconfusion". Wrong order does not tend to confuse.
 
In this case, the wrong order confuses ChemDraw. ;-)
It puts the N,N-dimethyl on the wrong N.
 
I can imagine that programming name to structure is hard.

To prevent unuseful comment alerts to this question author, e.g. chemistry.meta.stackexchange.com/q/3077/544 can be used for comment testing. :) — mykhal 29 secs ago

Q: Forcing italic for e.g. R/S stereodescriptors in comments

mykhalFor some special border cases, syntax formatting does not work as expected. E.g. trying to italicize “R” stereodescriptor in “(2R)-butan-2-ol” in a comment, with (2*R*)-…, (2_R_)-… or (2<i>R</i>)-… syntax, none works. Is there a trick for that?
