I believe you have to do this using a 'Requests Dialog' which is available only through JavaScript. See below page for more information and examples of how to do this:

It is only possible with the JavaScript popup, and there is a limit of how many requests you can send. Sending an app request to ALL your friends at once is considered spam anyway, you should never do this even if it would be possible.

https://developers.facebook.com/docs/reference/dialogs/requests/

You can, of course, use the "to" parameter to specifiy the friends you want to send the request to:

function sendRequestToRecipients() {
 FB.ui({method: 'apprequests',
    message: 'My Great Request',
    to: '499802820,499802852'
  }, requestCallback);
}
