Talk:Gutmann–Beckett method

Please rewrite Figure "Interaction of triethylphosphine oxide with a Lewis acid" (-) should be at "O" atom (especially it is negative in its ylide form) whereas (+) should be at "L.A." (because Lewis acidic center can not be negative in general). Besides that, an electronic pair can not be donated from positive atom to negative one. — Preceding unsigned comment added by 193.233.4.4 (talk) 13:11, 29 October 2020 (UTC)
