Pyrroles functionalised with a thianthrenium or diphenylsulfonium group undergo Stille couplings with aryl or alkynyl stannanes in good yields, avoiding the issues of instability that can hamper the use of the analogous pyrrolyl halides.

COP18 - Doha Climate Conference

An overview of the Climate Change Conference (also known as COP 18), held in Doha, Qatar in December 2012.

Predictably and sadly, the same issues have resurfaced: lack of media coverage, West stalling on doing anything, lack of funding, disagreement on how to address it, etc.

This page is an overview of the Doha Climate conference. It also includes a feed of latest news stories from Inter Press Service’s coverage of the conference.

After Doha, what next for Opec?

Most Opec countries attended along with non-Opec leaders such as Russia and Oman. It seemed that the previously announced deal to freeze production at January levels was a formality, especially as most countries involved could not or would not increase output anyway. But at the last moment the Saudi position changed, and it became clear they would not agree to freeze production unless Iran were included.

Brookings Doha Energy Forum Report 2014


Major changes in geopolitics, political economy, and energy markets are altering the global energy landscape. A potential nuclear deal with Iran has raised the possibility of new supplies coming online, and ongoing political gridlock in Iraq has hampered the country’s ability to expand supply. The U.S. energy boom is increasingly viewed as a long-term phenomenon, while a prolonged crisis in Ukraine threatens to impact Russian gas supplies to Europe.

How will the political developments in Iraq and Iran affect oil supply? What will be the impact of the Ukraine crisis on Europe, Russia, and China? How will these shifts help shape the energy markets of tomorrow?

Read the paper online: Brookings Doha Energy Report 2014

The 2014 Doha Energy Forum convened prominent industry experts and policymakers from Asia, the Middle East, Europe, and the United States for an in-depth dialogue on the rapidly changing global energy landscape. Based on the Forum’s plenary and roundtable sessions, this paper from the Brookings’ Doha Center and Energy Security Initiative reflects much of the discussion and debate around these changes. It also outlines the complexity of today’s energy markets and the geopolitical factors that set them in motion.

Brookings Doha Energy Forum Report 2015


From the rapid fall in oil prices to the conflicts that have threatened key energy sources and transit routes in the Middle East and North Africa, the global energy landscape has shifted dramatically over the past year. The change of a single number – the price of a barrel of crude oil – can carry profound implications for government policies and company decisions around the world, from efforts at subsidy reform to shale oil extraction. Understanding the interplay between key geopolitical events and energy markets remains crucial.

Has Asian consumers’ growing dependence on Middle Eastern energy supplies prompted greater interest in providing for the region’s security? How will new sources and new transit routes reshape the global LNG and natural gas landscape? What has been the impact of falling energy prices on unconventional production and investment in renewable energy resources?

At the fourth annual Brookings Doha Energy Forum, experts and policymakers from around the globe met to discuss the key global energy trends. In broad plenary sessions and focused roundtable discussions, industry leaders from the Middle East, Europe, Asia, and the United States wrestled with these and other questions. The findings of these many conversations are reflected in this report, jointly prepared by the Brookings Doha Center and the Energy Security and Climate Initiative.

Four Seasons Hotel Doha Unveils Complete Redesign by Pierre-Yves Rochon

Following the Hotel's reopening on 1st March 2020, Four Seasons Hotel Doha has unveiled the details of its complete interior design overhaul, courtesy of award winning and world-renowned interior designer, Pierre-Yves Rochon (PYR). Following extensive renovations of the guestrooms, suites, floors, lobby and dining outlets, the Hotel has been reshaped into an unmatched luxury destination at the heart of Qatar's capital city. Within this urban sanctuary, a refreshed colour scheme, including a rich spectrum of blues and beige in the guestrooms, evoke the earth, sprawling skies and Gulf views of Doha, while verdant colors and patterns in the new Tea Lounge pay homage to the splendours of nature. The redesign continues to establish an elevated sense of place and time through a blend of classical and contemporary elements, and touches of Middle Eastern influences from the region, visible through the opulent and colourful chandeliers as well as the ornate furniture detailing.
