Because it's not needed by many people.

You can always create a Photoshop droplet and then run it as a post processing step (bottom of LR's export dialog).

Perhaps I'm misunderstanding what it is you're trying to do but there's no problem with saving a grey-scale (ie, B&W) TIFF file from Lightroom and no export to Photoshop is necessary in order to do it.  I assume you're starting with a colour RAW or DNG image.  Convert it to B&W in the develop module.  Switch back to the library module when done.  Click the Export button, lower left corner of screen.  In the export dialog box select your destination folder, scroll down to the File Settings section and switch from the default jpeg to tiff using the Image Type pull-down menu.  Make any other settings you need, hit the Export button in the lower-right corner of the dialog box and you're done.

He says "Greyscale mode".

True, the method I suggested produces a monochrome image but still in RGB mode.

The problem is that when i have finished all the editing of the photo in LR ,I want to export a TIF file in grayscale , Gray gamma 2.2 ,
in order not to have a huge file.By the way ,I think that this may interest many people who may want  to send "lighter" than RGB files
(by mail for example) since the quality is not affected from the conversion.I still do not understand why this possibility is not included in LR.

Is a high-rate JPEG file not sufficient for your needs? (JPEG should be able to compress non-colored rgb images approximately as well as true tray-scale images).

I have read your comment but i do not think is sensible unless this conversion is very difficult to be achieved technically.(I apologise for my English)

Thank you.I have many workarounds to do this (convert in PS6 for example) but i want to know why it is not possible directly out LR .

Really, I've given you the reason - there is little demand for it. There's much more demand for CMYK, for example. Those who really need Grayscale Mode are usually those who also have Photoshop and can create an action or droplet:

  • In PS, create a new document and record an action with one step - Image > Mode > Grayscale
  • In PS, File > Automate > Create Droplet
  • Point it to your action
  • In Destination, choose Save and Close
  • Save the Droplet to your desktop
  • In Lightroom, Preferences, Presets, Show LR Presets folder
  • Should now be in Finder/Explorer, so go into this Lightroom folder and Export Actions
  • Move the Droplet into this folder
  • Restart LR
  • Export a file and at the bottom of the export dialog notice the Post Processing section
  • From its dropdown list, choose your Droplet and click OK
  • Once the file has exported, PS should open it, make it Grayscale Mode, and save and close it
