Abstract
We report rare examples of exclusive benzylic C–H oxidative addition in industrially important methylarenes using simple η4-arene iridium complexes. Mechanistic studies showed that coordinatively unsaturated η2-arene intermediates are responsible for the selective activation of benzylic, not aromatic C–H bonds and formation of stable benzyl complexes after trapping with a phosphine ligand.

Downtown Sounds
Downtown Sounds
Downtown Sounds started as a small gathering hosted in an alley, turning the underutilized space into something extraordinary. And extraordinary it became. With each year the event grew, now taking up two entire city blocks on Bay and Prospect Streets. Downtown Sounds draws bands from across the country and folks from Whatcom County and beyond to share in their love of music. After 17 years of this beloved, award-winning, urban music festival, it is firmly cemented as Downtown Bellingham's hottest summer attraction.
2021 Series Lineup and Schedule:
August 4:Nite Wave with Analog Brass
August 11: Eldridge Gravy & the Court Supreme with Mind’s Eye
August 18:High Step Society with Stephanie Anne Johnson & The Hidogs
August 25: The Dusty 45s with Nuages
Beer garden opens at 5:30pm. Music from 6:00-9:00pm. Back on Bay & Prospect Streets.
Community Health & Safety
After June 30, 2021 physical distancing and capacity limitation restrictions were lifted for outdoor events. However, due to growing concern regarding the Delta variant, we have a few guidelines for Downtown Sounds concerts.
Guidelines:
Please stay home if you are sick, or if you’ve been in contact with someone who is sick.
Face coverings are required for any concert attendees who are unvaccinated, and all attendees are encouraged to bring a mask.
Whatcom County Health Department recommends individuals wear a mask or face covering during crowded outdoor events, like Downtown Sounds
Ultimately, getting vaccinated and wearing a mask is the best way to help keep our community healthy. Please be considerate of others while enjoying Downtown Sounds, and thank you for continuing to keep each other safe!
Holly Street closure:
To allow for more space among concert goers, we’ll be closing Holly Street to through traffic on Wednesdays in August so that we can all enjoy the music with a little more space to spread out.
Downtown INSIDER perks
Downtown INSIDERS skip the beer garden line at every concert, all summer long. This year, new INSIDERS who sign up at the $10+ level will enjoy their first drink token included with registration, which can be used for a glass of beer, wine or cider!

Every year around the 8th day of the 8th month (August 8th), there is a cosmic alignment called “The Lions Gateway.” At the Lions Gate there is increased 2021 - Free Activators energy flowing between the physical and spiritual realms.
The Lions Gate, with ties to ancient Egypt, has been observed and honored as a time of a great energetic influx and activation for thousands of years.
At this time, there is an alignment between the Earth and the star Sirius. As Sirius rises in the sky, Orion's Belt directly aligns with the Pyramid of Giza, and from our perspective on Earth, it appears that Sirius (the brightest star we can see) comes closer to the Earth.
The star Sirius, which represents abundance, harvest and fertility, is twice the size of our Sun and 26x brighter! It is a big source of spiritual light on the inner planes.
This alignment is called the Lions Gate, or Lions Gateway, because it occurs when the sun is in the astrological sign of Leo (the Lion). As a Zodiac Sign, Leo is associated with the heart center and represents the individualized expression of the Divine.
The Panel will share about the Lion's Gate, Then participants may ask the Panel anything, not only about the theme, and we'll partner with and empower you with insight and tools so you'll - maximally Activate during this Alignment - and make it through the blocks, twists and turns on your path.
