An aldol condensation is an organic reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a Î²-hydroxyaldehyde or Î²-hydroxyketone, followed by a dehydration to give a conjugated enone. Aldol condensations are important in organic synthesis, providing a good way to form carbonâcarbon bonds.For example, the Robinson annulation reaction sequence features an aldol condensation; the Wieland-Miescher ketone product is an important starting material for many organic syntheses.owever, the aldol reaction is not formally a condensation reaction because it does not involve the loss of a small molecule. The reaction between an aldehyde/ketone and a carbonyl compound lacking an alpha-hydrogen (cross aldol condensation) is called the Claisen-Schmidt condensation.
Steelers' Tomlin, youngest coach to win Super Bowl, signed through 2012 with option year
Hereâs a complete look at all the quarterback-head coach duos who made it to at least two Super Bowls, ordered by most appearances. Tom Brady and Bill Belichick, New England Patriots: 6 Super Bowl appearances; 4 wins. Terry Bradshaw and Chuck Noll, Pittsburgh Steelers: 4 Super Bowl appearances; 4 wins. Roger Staubach and Tom Landry, Dallas Cowboys: 4 Super Bowl appearances, 2 wins (Note: This would be five appearances if you count Super Bowl IX, in which Staubach didnât play.
